Hex wrenches, also known as Allen keys, are indispensable tools in various industries and DIY projects. However, the dreaded moment when a hex wrench snaps can leave you stranded and frustrated. Fortunately, there are several effective methods to remove broken hex wrenches, restoring your project’s progress.
Methods for Removing Broken Hex Wrenches
1. Pliers
Using pliers is a straightforward method for removing broken hex wrenches. Grasp the broken end of the wrench with the pliers and gently twist and pull. Avoid applying excessive force, as this could damage the surrounding material.
2. Vise Grip
A vise grip provides a more secure hold than pliers. Clamp the broken end of the wrench in the vise grip and apply gentle twisting and pulling motions. The vise grip’s serrated jaws will ensure a firm grip.
3. Easy-Out Screw Extractor
Easy-out screw extractors are specifically designed to remove broken screws and bolts. Insert the extractor into the broken hex wrench and turn it counterclockwise. The extractor’s reverse threads will engage with the wrench, allowing you to extract it.
4. Reverse Drill Bit
A reverse drill bit is an effective method for removing broken hex wrenches that are deeply embedded. Drill a small hole into the broken end of the wrench using a reverse drill bit. The bit will cut into the wrench, creating a groove that you can use to extract it.
5. Hammer and Chisel
If the broken hex wrench is accessible from the side, you can use a hammer and chisel to extract it. Place the chisel against the broken end of the wrench and tap it gently with the hammer. The vibrations will loosen the wrench, allowing you to pull it out.
6. Heat and Cold
Applying heat to the broken hex wrench can expand the metal, making it easier to remove. Use a heat gun or torch to heat the wrench for a few seconds. Once heated, grasp the wrench with pliers and pull it out. Alternatively, you can apply cold to the wrench using an ice pack or liquid nitrogen. The cold will shrink the metal, creating a gap between the wrench and the surrounding material.
7. Dremel Tool
A Dremel tool can be used to create a slot or groove in the broken hex wrench. Insert a screwdriver or flathead bit into the Dremel tool and gently cut a slot into the wrench. Once the slot is cut, you can use a screwdriver or pliers to extract the wrench.
Safety Precautions
When removing broken hex wrenches, always wear safety glasses to protect your eyes from flying metal fragments. Use caution when applying heat or using sharp tools, as these can cause burns or cuts.
Final Note
By following these methods, you can effectively remove broken hex wrenches, restoring your project’s progress. Remember to exercise caution and use the appropriate tools for the job. With a little patience and ingenuity, you can conquer the challenge of broken hex wrenches.
