How to Repair a Damaged Gun Screw [Step-by-Step Guide]

Have you ever tried to repair a damaged gun screw and felt like you were in over your head? 

Unfortunately, gun screws are prone to damage and can become stripped, bent, or worn out over time. 

In these cases, knowing how to repair a damaged gun screw is essential to keep your firearm in good working order. 

This article will provide you with the steps to take when repairing a damaged gun screw, as well as some tips for avoiding damage in the first place.

Types of Damaged Gun Screws

Several different types of damage can affect gun screws. 

Stripped screws are caused when a screwdriver slips while trying to tighten or loosen the screw, leading to a loss of grip and the inability to turn the screw. 

Bent screws typically occur when a screwdriver is used with too much force, causing the head of the screw to bend or break off. 

Finally, worn-out screws are caused by repeated use over time, leading to material degradation and eventual failure.

Tools and Materials

Repairing a damaged gun screw can be tricky. Depending on the size and type of gun screw, the tools and materials needed to fix it properly will vary. 

However, there are some basics that all gunsmiths should have on hand when attempting any gun screw repair.

First and foremost, you will need a quality screwdriver set that is compatible with the gun screw. This set should include a flathead screwdriver and a Phillips head screwdriver, as well as an Allen wrench for any screws requiring a hexagonal head. 

Additionally, a small set of needle-nose pliers will come in handy for removing or adjusting small parts.

You will also need a sound file on hand. These should be sized appropriately for the gun screw you are repairing, as it is essential to file down the head of the screw evenly.

Thirdly, you will need some lubricant, such as gun oil, to ensure that the gun screw can move freely. This will also help protect against rust and corrosion.

Finally, you may need to purchase a replacement gun screw if the old one is too damaged to be repaired. Choosing one that is the same size (not a larger screw or a tiny screw) and typing as the original is essential, as a wrong fit can cause further damage.

How to Repair a Damaged Gun Screw

Here are the three different types of screws and how to fix them.

Stripped Screw

If you have a stripped screw, the first step is to try to remove it with a screwdriver. If the screw is still tight and won’t turn, you can apply some force with a pair of pliers or locking pliers. 

Alternatively, you can use a thread repair kit for the stripped screw. Thread repair kits are designed to repair stripped screws by inserting a new thread into the head of the screw. 

To use a thread repair kit, start by drilling a small hole into the head of the stripped gun screw. Then, use the thread repair kit to insert a new thread into the hole. 

Once the new thread is inserted, you can use a screwdriver or wrench to unscrew the gun screw.

After this, you will need to add a replacement gun screw. 

Bent Screws

Fixing a bent gun screw can be tricky, but it is possible. Depending on the severity of the bend, you may be able to use a simple pair of pliers to straighten it out. 

You might need to use specialist tools and methods to complete more severe bends.

The first thing you should do is determine how severe the bend in the gun screw is. You might be able to gently bend it back into shape using a pair of pliers if it is only slightly bent.

You must be extremely careful not to use too much force or risk snapping off the screw’s head. You’ll usually need professional tools and methods to correct a more severe bend.

You must take the gun screw out of the firearm. It has a stubborn screw that’s. For this, a screwdriver that matches the screw’s size and type is necessary. Once you have removed the screw, you can begin the process of fixing the bend. 

The best way to fix a severely bent gun screw is to use a vice, which is a type of clamping device. To do this, place the bent screw in the vice and then tighten it until the screw is firmly held in place. 

You can then use a hammer to gently tap the bent end of the screw in the direction you want it to go. This should help to straighten the screw out. 

Once the gun screw is straightened out, you will need to re-install it into the gun. Be sure to use a screwdriver that is the correct size and type for the screw. 

Worn Out Screws

Fixing a worn-out screw is easier to do than the other two screws. 

The screw must first be removed using a screwdriver, and then it must be filed down.

With a small metal file, flatten and smooth the screw’s head, paying close attention to any possible chips or cracks. To restore the screw’s head to its original shape, you might need to use a few different filing strokes.

After that, you can use some steel wool to get rid of any rust that might still be there.

Finally, use a screwdriver to tighten the screw back into place after lightly lubricating the screw’s threads with oil or another lubricant. Make sure the screw is tightened correctly, but do not over-tighten it.


If the gun screw is stripped, bent, or worn out, it may be necessary to re-thread it. 

This can be done with a tap and die set, a tool used to cut threads into the head of a screw. 

This process should only be done by a qualified gunsmith, as it requires high skill and precision.

Installing the New Screw

Installing a new screw may be necessary for severe cases involving a broken screw or if you don’t want to put in the effort to repair your existing ones. This can be done with a screwdriver that matches the size and shape of the screw. 

Make sure to apply even and consistent pressure while turning the screw, as this will help to ensure that the screw is tightened correctly.

Tips for Avoiding Damage

Gun screws can be protected from damage by following a few straightforward steps. To lessen the chance of slippage, use the appropriate size and kind of screwdriver for the screw.

Additionally, be careful not to overtighten or under-tighten screws, as this might result in bending or breaking.

Finally, to help identify any issues before they worsen, routinely check gun screws for signs of wear or corrosion. Catching problems early on will save you a lot of different issues.

Last Words

Gun screws can become damaged over time due to wear and tear or improper use. Knowing how to repair a damaged gun screw is essential to keep your firearm in good working order
