How Do You Remove A Broken Screw

How to Remove a Stripped or Broken Screw: A Comprehensive Guide

Removing a stripped or broken screw can be incredibly frustrating, but with the right tools and techniques, you can successfully extract it without causing further damage. This guide covers various methods for removing broken screws, from simple solutions for slightly damaged screws to more advanced techniques for stubborn, completely broken screws. This article will help you navigate common screw removal challenges and get the job done efficiently.

What to do before you start:

Before attempting any removal method, it's crucial to assess the situation. Identify the type of screw (Phillips, flathead, Torx, etc.), its size, and the material it's embedded in (wood, metal, plastic). Understanding these factors will help you choose the most appropriate tool and technique. Take photos to document the situation, this can be helpful if you run into problems.

Methods for Removing a Stripped Screw

1. Increased Grip Methods:

• Rubber Band: Place a rubber band over the screw head. The added friction will help your screwdriver grip better. This simple trick works wonders for slightly stripped screws.
• Toothpaste or Soap: Apply a small amount of toothpaste or soap to the screw head. The added lubrication improves grip and reduces friction. Let it sit for a few minutes before trying again.
• Hammer and Chisel (for Flathead Screws): Carefully chisel into the screw head's slot, creating a new, deeper slot. This method risks damaging the surrounding material, so use caution.

2. Screw Extractors:

Screw extractors are specialized tools designed for removing broken or stripped screws. They are available in various sizes and types:

• Left-Handed Drill Bits: These drill bits are designed to reverse their way into the screw, removing it. Drill carefully to avoid further damage.
• Screw Extractor Sets: These kits contain multiple extractor sizes and usually include a drill bit for creating a pilot hole. Choose the correct size extractor that is slightly smaller than the screw's diameter.

Procedure for Using Screw Extractors:

1. Drill a Pilot Hole: Carefully drill a small pilot hole into the center of the stripped screw. The pilot hole should be slightly smaller than the extractor you plan to use.
2. Insert the Extractor: Carefully insert the screw extractor into the pilot hole. Turn it clockwise (righty-tighty, lefty-loosey doesn’t apply here because the extractor is left-handed).
3. Apply Pressure: Gently apply pressure while turning counter-clockwise to loosen and remove the screw. If it gets stuck, add some penetrating oil and try again.

3. Using a Dremel or Rotary Tool:

For extremely stubborn screws, a Dremel tool can be helpful. You can use a small cutting disc or grinding bit to carefully create a new slot or notch in the screw head. This allows you to use a flathead screwdriver to remove the screw. Remember to use safety glasses and take precautions to avoid damaging the surrounding surface.

Methods for Removing a Broken Screw (Screw Head is Gone)

1. Drill and Tap (For Metal):

This is a more advanced method but effective for metal parts.

1. Drill out the screw: Drill out most of the broken screw, carefully avoiding surrounding material.
2. Tap the hole: Use a tap (a tool used to cut threads) to create clean new threads.
3. Screw in a new screw: Screw in a new screw of the correct size and type.

2. Using a Screw Extractor (For Metal or Wood):

Screw extractors are also useful for removing broken screws. Drill a pilot hole carefully and work your way up to a larger extractor bit if needed. Patience is key!

3. Chemical Methods (For Metal):

Penetrating oils like Liquid Wrench or PB Blaster can loosen stubborn screws. Apply the penetrating oil generously, let it sit for several hours (even overnight), and try removing the screw with appropriate tools.

Preventing Stripped Screws in the Future:

• Use the right size screwdriver: This is crucial. Using a screwdriver that's too small or too large will increase the chance of stripping the screw head.
• Apply proper pressure: Don't force the screwdriver. Use steady, even pressure.
• Use a good quality screwdriver: Cheap screwdrivers are more prone to slipping.
• Keep your tools maintained: Sharp, well-maintained tools are essential for preventing stripped screws.

Remember to always prioritize safety. Wear safety glasses and work in a well-ventilated area, especially when using power tools and chemicals. If you're unsure about any of these methods, it's always best to consult a professional. With the right approach and a little patience, you can conquer even the most stubborn broken screws!
