If you’re stuck with a screw that has no head, there are several ways to remove it. Some of these methods are simple, while others require more effort.
The first method to try is to drill a hole in the damaged screw. This will make it easier to remove the screw.
Drill a Hole
There are a few ways to remove a screw with no head, but the most common is to drill a hole in it. This can be done in both wooden and metal screws.
To drill a hole, you need to first select a drill bit that is small enough to fit in the head of your stripped screw. Next, insert the bit into your drill and tighten it securely.
Then, apply a drop of cutting oil on the screw head and slowly drill into the surface. This will create a hole in the head of your stripped screw and make it easier to remove the screw.
Once you’ve drilled a hole, it’s time to use your screw extractor. To do this, choose a left-hand drill bit that is slightly smaller than the screw you want to remove.
Weld a Nut
If the head of a screw is broken and you need to remove it, you can weld it in place instead. This method is a little more time-consuming, but it can be done and it’s a good way to prevent damage to the threads of the bolt.
This method is best if you have a MIG welder, but it can also be done using a regular arc welder. Just make sure to wear the proper welding gloves and mask while you weld.
Tap the Screwdriver
If your screw has lost its head and you need a quick way to remove it, there are several options. Some of these include tapping the screwdriver deeper into the screw, using a rubber band or twisting it out with locking pliers.
Another option is to use a drill bit designed for metal to tap into the screwhead. This can help your screwdriver reach deeper and achieve a better grip on the stuck fastener, but you should only drill a small hole.
Alternatively, you can try using a screw thread starter like Twist-a-Nut(tm). They create, repair and clean out threaded holes, reform damaged threads, and smooth off burs. They’re usually available in multiple tap sizes, so they can be used for a wide range of screw types.
Break the Screw
A screw head can get stripped and broken due to various reasons including oxidation, age and pressure. This can make it difficult to remove the screw.
Fortunately, there are several ways to remove a screw with no head without damaging the surface more than necessary. These techniques include using a different size of screwdriver, adding lubricant to the screw, and applying heat to the broken head.
Another method is to weld a nut onto the top of the screw. This can help loosen the stuck screw head and allow you to extract it by hand.
The key to this hack is to ensure that the nut is firmly placed over the screw and is of the correct size. You can also add additional help by welding it at a high temperature.
If none of these methods work, a specialized tool called an extractor might be the best solution. This tool has reverse threading, allowing you to unscrew the screw by rotating it counterclockwise.
