Assess the situation
Before attempting to remove a broken screw, it is important to assess the situation and determine the best approach. Consider the size and type of screw, the material it is stuck in, and the tools available to you. This will help you select the most suitable method for removing the broken screw.
Use a screw extractor
A screw extractor is a specialized tool designed specifically for removing broken screws. It features a spiral-shaped flute that grips onto the screw when turned counterclockwise, allowing it to be pulled out. To use a screw extractor, start by drilling a small hole into the center of the broken screw. Then insert the extractor and turn it counterclockwise using a wrench or a screwdriver. The extractor will grip onto the screw and allow you to remove it.
If the broken screw is stuck due to corrosion or adhesives, applying heat can help loosen it. Heat causes the metal to expand, which can break the bond between the screw and the material it is stuck in. You can use a heat gun or a small torch to apply targeted heat to the area around the screw. Once the metal has expanded, you can try removing the screw using pliers or a screwdriver.
Try pliers or a screwdriver
If the broken screw has enough protruding length, you can attempt to grip it with pliers and unscrew it. Use a pair of locking pliers or needle-nose pliers to firmly grip the exposed part of the screw. Slowly turn counterclockwise to remove the screw. Alternatively, you can try using a screwdriver with a good grip to turn the broken screw. Apply downward pressure while turning to ensure a secure grip on the screw.
Drill out the screw
If all other methods fail, you may need to resort to drilling out the broken screw. Start by selecting a drill bit slightly smaller than the diameter of the screw. Carefully drill into the center of the screw, being mindful not to damage the surrounding material. Once the drill bit has gone through the screw, switch to a slightly larger bit and continue drilling until the head of the screw is completely removed. Use pliers or a screwdriver to remove any remaining debris.
