How to Remove a Stripped Screw or BoltUpdated 34 minutes ago

Overview

This article explains three effective methods to remove a stripped screw using common tools: the Torx method, a rotary tool and flat-head screwdriver, and an extractor bit. You'll learn step-by-step instructions for each method, including tips for improving grip and links to demonstration videos.

Before You Begin

• Gather the required tools for your chosen method:
  • Torx heads, small hammer, and heat source (for Method 1)
  • Rotary tool with disc attachment and flat-head screwdriver (for Method 2)
• Extractor bits, centre punch, drill, and hammer (for Method 3)
• Ensure you have safety equipment such as gloves and eye protection
• Work in a well-ventilated area

Method 1: Torx Method

This is the easiest method if you have a set of Torx bits. You may also need a small hammer and a heat gun or hair dryer.

1. If the socket is warped from cross-threading, drill a small hole. If the hole can already fit a snug Torx bit, skip this step.
2. Find a Torx head that fits tightly into the stripped screw.
3. Attach the Torx head to a screwdriver. Using a small hammer or hard mallet, tap the Torx bit into the screw to create grip.
4. Apply a small amount of heat to the exterior area using a heat gun on low or a hair dryer. This helps loosen the screw.
5. Unbolt the stripped screw. Replace it with a new one once extracted.

💡 Tip: Applying heat can help expand the metal and make extraction easier.

Method 2: Rotary Tool and Flat-Head Screwdriver

This method is useful if you have access to a rotary tool.

Demonstration Video: See 1:37 in the referenced video.

Tools Needed:

• Rotary tool with disc attachment
• Flat-head screwdriver

1. Use the rotary tool with a disc attachment to grind a straight slit into the head of the stripped screw.
2. Insert a flat-head screwdriver into the new slit and unscrew the stripped screw.

Method 3: Extractor Bit Method

Extractor bits are specifically designed for removing stripped screws, though they can be expensive.

Tools Needed:

• Extractor bits
• Centre punch bit
• Drill with appropriate bit size
• Hammer

1. Check if the stripped screw’s hole is large enough for the extractor bit. If not, drill slightly (2–5 mm is safe) to provide enough grip.
2. Use a centre punch to create a starting hole in the screw.
3. Drill a small portion into the screw, just enough for the extractor bit size.
4. Insert the extractor bit into the hole, hammer it in gently, and then extract the screw.

⚠️ Note: Extractor bits can be expensive, but they are highly effective for stubborn screws.

Troubleshooting

Issue: Torx bit slips or cannot grip

Solution: Ensure you use the correct size Torx bit. If the screw head is too damaged, try Method 2 or 3.

Issue: Extractor bit does not grip or breaks

Solution: Make sure the hole is the correct size for the extractor bit and use a centre punch for better alignment. Avoid excessive force to prevent breaking the bit.

Additional Information

• Always replace stripped screws with new ones to ensure proper fastening.
• Use caution when applying heat to avoid damaging surrounding materials.
