Overtightening, rust, or cross-threading can cause a rigid screw or bolt to become seized. Easy Out bolt or screw extractors can be used to remove the stubborn screw or bolt. When appropriately utilized, easy out can save you money and time by avoiding more expensive and time-consuming procedures like re-boring and re-tapping, which often require the assistance of a technician.
Anyone who has ever driven a screw knows how quickly screw heads can strip away. You won’t be able to drive the screw any further in or pull it out if this happens. This may force you to restart your project at that moment.
You might also invest in a screw extractor (easy out). Screw extractors are tools that are used to extract broken screws or nuts. They often drill bits or impact driver bits that fit into your cordless drill or impact driver. An “easy out” is another name for a screw extractor. They truly make a complex problem simple. This step-by-step instruction to using easy out correctly should help anyone who has to remove a broken or seized screw or bolt.

What Exactly Is A Screw Extractor (Easy Out)?
A screw extractor (easy out) may appear to be a standard drill bit at first view, but closer inspection reveals that the spiral flutes are closer together and, more importantly, run in the opposite direction. The screw extractor (easy out) features a square head that may be gripped with a socket wrench and is also bulkier. It’s forged from chrome-vanadium steel or another similarly robust material and available in a range of diameters to handle a variety of different-sized screws.
The screw extractor (easy out) has a pointed tip and a conical overall shape. The flutes bite into the metal and grab it when you tap the extractor into a pre-drilled hole in the screw head. Because the flutes spiral counterclockwise, rotating the extractor in that direction enables them to dig even deeper while also causing the screw to back out of the workpiece.
Design Of The Screw Extractor (Easy Out)
A screw extractor (easy out) has a square head on one end and reverse tapered cutting screw threads on the other. It is made of high-strength steel. The square head of the extractor fits into a T-handle that is used to turn it. Locking pliers can also be used to hold and turn the tool’s head.
The tool’s sharp end is made up of tapered threads. After a pilot hole has been drilled, these are designed to screw backward (counterclockwise) into the head of the screw or bolt. The extractor’s end is steeply tapered, allowing it to dig deeper and tighter into the damaged screw as it is spun. As you turn the extractor counterclockwise, it digs deeper and deeper into the damaged screw as the damaged screw backs out.
When utilizing a screw extractor (easy out), a T-handle comes in handy. The handle is so named because it fits over the end of an extractor bit. T-handles come in a number of sizes to accommodate a variety of extractors, and many of them can also be used with taps to thread holes. If you don’t have a T-handle, you can use locking pliers to turn a screw extractor.
How Do Screw Extractors (Easy Out) Function?
It’s easy to use a screw extractor (easy out). To begin, drill a pilot hole through the broken screw or bolt. The opposite hand thread extractor must then be threaded in. The extractor can be utilized as an extension of the screw or bolt once it has reached the full depth of the thread. This makes it possible to simply remove it from the object.
HSS, alloy steel, carbon steel, and hardened chrome vanadium steel are common materials used in these tools. This sturdy construction, combined with their spiral flutes design, makes them perfect for removing a wide range of screws, studs, bolts, and fasteners. Screw extractors (easy out) come in a variety of sizes to fit different fastener sizes, and most screw extractors can handle medium-tensile-strength fixing.
What To Look For When Purchasing A Screw Extractor (Easy Out)?
Choose a screw extractor with wide, aggressive grooves when you’re shopping. The gripping power of an extractor originates from these grooves or flutes. The extractor will have an easier time cutting through the screw and gripping it if they are wider.
To tighten its grasp on the screw, a screw extractor uses left-handed grooves. This means that the tighter the easy out’s grip gets, the more complex the screw gets. Another thing to check is whether the easy out is composed of hardened steel or not. Some screws and bolts are hardened, and removing them will require a hardened screw extractor.
Removing Damaged Screws With A Screw Extractor (Easy Out)
To remove a screw, first pound the screw extractor into the head of the screw until the flutes bite, then turn the extractor counterclockwise with a wrench or drill. To give the extractor something to grab, you usually need to drill a 1/8-inch deep hole in the screw, but this isn’t always necessary. A stripped Phillips or Robertson screw can occasionally be extracted by simply tapping the point of the extractor into the stripped screwdriver slot.
A bar handle is commonly included in screw extractor kits to provide leverage when turning the extractor. However, because you can exert downward power on the drill while it’s turning, placing the extractor into a drill and running it in reverse is nearly always more accessible and more efficient. This allows the extractor to penetrate the metal a little deeper and prevents it from slipping. When retrieving larger screws from metal, however, the bar is preferable.
If the screw is rusty, the head of the screw may break off when you try to remove it. This is normally not a problem; however, you may need to use a more significant bit to expand the screw hole so you can drill a new pilot hole in the screw shank and drive the extractor into it. When a screw has rusted in place, it’s a good idea to lubricate it well and wait 10 to 20 minutes before removing it.
How Do I Prepare The Screw?
Make sure the screw is in good condition before beginning to withdraw it. There are several things you can do to prepare.
- To begin, use a center punch to punch a hole in the screw. The center punch is designed to seem like a metal pen. It may be found at any local hardware shop. Place the punch tip against the middle of the problematic screw head with one hand.
- Then, take a hammer and strike the punch’s head with the other hand. With a delicate touch, tap it. You should see a small indentation in the screw if you followed the procedures correctly. The drill bit is directed into the screw’s core in this step.
- After that, apply the thread-cutting lubricant to the screw. This oil is available in large bottles at a number of hardware stores. However, for a project, just one drop is required.
- The liquid will lubricate the metal. You’ll spend significantly less time drilling as a result. In addition, the drill bit can be used for a longer amount of time. If you can’t find the lubricant, you can use motor oil or household oil instead. However, it does not have the same cutting power as actual cutting oil.
- Apply the penetrating oil to the screw after that. This oil aids in loosening the screw and allows it to be readily removed. The oil can also be used to remove rusted screws from a metal surface. Use acetone instead of penetrating oil if you can’t get your hands on penetrating oil.
How Do I Use A Screw Extractor (Easy Out)?
The procedure for using a screw extractor (easy out) is broken down into seven steps:
- Choose a drill bit
- Set the drill bit in place
- Create a hole
- Push the extractor through the hole
- Twist the extractor to get the most out of it
- Preheat the screw
- Remove the screw
Each stage has its own set of requirements and recommendations for reaching the best possible outcome. Let’s take a look at them more closely.
Step 1: Choose A Drill Bit
Select a drill bit that is somewhat smaller than the target screw to begin. Insert the drill bits into the screw or fastener to be removed. It must be narrower than the screw tip to be appropriate. Once you’ve found the right one, connect it to your drill. The drill bits can be purchased at a reasonable price. Alternatively, you can buy a whole set in a variety of sizes.
Step 2: Set The Drill Bit In Place
Now you must insert the drill bit into the previously created divot. Drill gently and carefully when you first begin. Excessive force may cause the screw to shatter. Drill accurately into the screw tip by keeping the drill bit tight.
Step 3: Create A Hole
Now is the time to drill a 3 to 6-millimeter long hole in the screw tip. The screw extractor (easy out) you use determines the depth. To examine if the screw extractor (easy out) matches the hole you drilled, bring it up to it. Drill until the hole is large enough for the extractor to fit. You risk harming the threads if you use a drill bit that only penetrates the screw.
Step 4: Push The Extractor Through The Hole
The extractor’s spiral head must go into the hole. Use a hammer to lightly tap the extractor to ensure that it can move in. You must hold on to the T-shaped handle on the extractor’s loose end during this stage. Then, counterclockwise rotate the tool until you can no longer turn it.
Step 5: Twist The Extractor To Get The Most Out Of It
In this step, use a drill or a wrench to twist the screw extractor (easy out). If you’re using a wrench, grab the extractor’s top. Continue counterclockwise twisting the screw until it comes loose. Connect the drill to the extractor’s free head if you want to use it. Then, using your drill, twist the screw counterclockwise. Only a little effort is required to remove the screw. Continue twisting the screw in different directions if it won’t come out.
Step 6: Preheat The Screw
If you’re still having trouble removing the screw, there’s another option. Lightly heat the screw with a butane or propane torch for one or two minutes. This is an optional step. Use it if your substance is non-flammable, such as metal. Then try to remove the screw once again. After the metal has been heated, it will expand, making it easier to remove.
Step 7: Remove The Screw
Finally, remove the screw with a plier. Clamping pliers have a more secure grasp on screws than regular pliers. The screw can be removed by turning the plier. The screw is also easier to withdraw with the help of heat. Drilling farther into the screw can potentially cause it to shatter or weaken. To avoid damaging the surrounding surface, proceed with caution.
Sizes Of Screw Extractors (Easy Out)
The bolts and screws should be the same size as the screw extractor (easy out). For convenience and ease of use, most screw extractors (easy out) come in packages with many tools of various sizes. This is great for experts and others who use removers of various sizes on a regular basis.
Here’s what you’ll need to know about screw extractor sizes from 1 to 6, and the corresponding diameter:
- 1: 5 to 8 millimeters
- 2: 10 millimeters
- 3: 10 millimeters
- 4: 12 to 16 millimeters
- 5: 16 millimeters
- 6: 20 millimeters
In regards to their differences, size 3 differs from size 2 in that it may accommodate a bigger pre-drilled size.
Why Do You Need A Screw Extractor (Easy Out)?
There are various advantages to using the screw extractor kit.
The most obvious benefit of using these things is the ease with which they may be used to deal with corroded, worn, or damaged bolts. It’s easier to replace the screws now that you have the tool. Extractors (easy out) can provide a quick and easy solution to this problem.
When you use an extractor (easy out), you don’t have to drill a bigger hole in the material. It means that the screw hole can be left at its original size. After you’ve successfully removed the broken screw, replace it with a screw of the same size. As a result, your final product will be sleek and tidy.
The screw extractor (easy out) can be used if the integrity of the prior thread needs to be preserved in the item. You can use the tool to replace the bolt with one that has the same thread measurement. You can avoid using a drill with the help of the screw extractor. As a result, there is no need to waste time repairing the hole to its original size. You are free to continue the prior thread.
Some Hints And Tips For Using A Screw Extractor (Easy Out)
- Because the depth of the hole determines the screw extractor’s performance, you don’t want too much debris to clog it. Keep the hole free of debris.
- The extractor should not be forced into the hole. It should be able to draw itself in.
- Use a drill with a handle so you can maintain a more secure grasp on the drill. Additionally, this will aid in the prevention of damage.
- Different sizes of extractors are included in extractor kits. Use a screw that is the proper size for the job.
What Type Of Screw Extractor (Easy Out) Should You Use?
Any mechanic who has used a screw extractor (easy out) will recall how a difficult task transformed into a catastrophic job when the extractor broke, erasing any possibility of a productive and profitable repair.
There are a number of commonly used methods for removing broken bolts and screws. Regardless of the fact that all of the following are “screw extractors,” many of them come up short.
1. Extractors With Straight Fluted Tapering
Straight fluted extractors are an inexpensive and quick way to remove a broken bolt or nut. They are typically imported from China and are made of low-cost steel that has been heat-treated to increase durability. A pilot hole is drilled, then a tapered, four-sided piece of hardened steel is hammered in to try to grab the inside of the drilled hole, as in most typical screw extractors.
The technician will then attempt to remove the remaining fragment by twisting the extractor counter-clockwise with a set of vice-grips or a wrench. The issue with these extractors is that the break-torque is frequently not defined due to quality variances, making it unreliable and unstable. Because they only grip the tangent of the inside drilled hole surface in two places, they can quickly lose their bite or, worse, break off in the residual set for removal.
2. Extractors With A Turn Nut Straight Fluted
Straight fluted or splined extractors with a turn nut are just as easy to install as a spiral fluted or straight fluted extractor, but they have a few major advantages. The technician will drill a hole in the broken stud or screw and then hammer in the flute. Six narrow sides, or splines, cut through the residue on these extractors, allowing for more points of engagement and surface area inside the pilot hole.
This type of extractor supports both clockwise and counterclockwise rotation, allowing a technician to free the broken fragment by simply spinning the extractor in either direction. They are significantly more effective. And because they have a wider cross-section at the sites of contact, they withstand breakage and have higher break-torque parameters. By inserting the slip nut over the spline, the technician will back out the stud.
The extractor with a turn nut has the advantage of not deforming the broken stud or bolt while giving an equal distribution of force and torque straight to the extractor while being more expensive than the other types.
3. Extractors With Spiral Fluted Tapering
Spiral fluted tapered extractors work similarly to straight fluted tapered extractors. Still, instead of hammering them in, they screw in by spinning the square head with a wrench or socket, sinking the extractor into the pilot hole of the broken bolt. The technician will next remove the remaining section of the fractured stud with a pair of vice-grips after it has been set. They bite on the tangent of the hole with minimal contact, similar to straight tapered fluted extractors.
Due to their capacity to merely bend the fractured remnant and actually press the bolt into the mating material, both types can make the extraction operation more difficult. Spiral fluted tapered extractors are better employed in tougher materials, despite being higher on the Rockwell scale than the two tapered versions. Harder material production, on the other hand, results in a more brittle extractor that is more prone to spontaneous breakage.
4. Drill Bits Left Handed
A damaged bolt or screw must be ground as flat as possible before using a left-handed drill bit to retrieve it. A center punch will then be used to apply a guiding point. The tech will then insert the left-handed drill bit into the chuck and reverse-drill the hole. The goal is for the drill bit to bite into the stud’s residue.
That sounds wonderful in theory, but depending on the condition of the shattered remnant, corrosion in the path to extraction may jam and lock the stud in, increasing the danger of fracturing the bit and complicating the repair.
When removing a bolt or stud when it fractures, a burr is commonly generated. This burr works in the same way as a split lock washer in that it bites into the mating material, increasing the torque needed to extricate it. Furthermore, when force is applied, the remnant bites in even harder. Straight flute extractors’ capacity to travel in both directions allows the technician to dislodge the extractor without deforming it, resulting in a more predictable and efficient repair.
Based on the application, each of these extractors is a useful tool. However, extreme caution should be exercised to avoid over-torquing the extractor. Quality is important with all tools, but it’s more important when completing a difficult repair. Finally, spline-type extractors are built in the United States, providing for greater consistency and making the technician more productive when working against the repair’s scheduled time.
Removing a screw or bolt can be aggravating if the screw’s slots or the bolt’s head have been broken during the removal process. If the fastener is rusted in place or you have used the wrong-sized tool, this can easily happen. A few slips of the screwdriver or wrench can damage the head of the screw or bolt, making it nearly hard to obtain a strong grip on it.
The screw extractor (easy out), a cunning little device, comes to your rescue. Screw extractors (easy out) are available in a variety of sizes to fit screws with diameters ranging from 3/32 inch to 1/2 inch. They’re suitable for a wide range of screws and bolts.
