How Do You Unscrew a Stripped Allen Screw 🔧 – Easy Fixes That Work

A stripped Allen screw doesn’t have to end your DIY project—there are reliable tricks to get it out without damaging your materials.

Stripped screws are one of the most frustrating problems for homeowners and DIYers. If you’re wondering how do you unscrew a stripped Allen screw, the good news is that there are several proven methods. With the right tools and a little patience, you can remove even the most stubborn stripped screw.

Why Allen Screws Strip

Allen screws, also called hex screws, are designed for torque and tight fastening. But they strip when:

• The wrong size Allen key is used.

• Excessive force is applied.

• Cheap or worn tools round out the screw head.

• Rust or debris prevents proper grip.

“Most stripped screws happen because of mismatched tools. Always use the exact hex size, not ‘close enough.’”

Methods: How to Unscrew a Stripped Allen Screw

Method	How It Works	Best For
Rubber Band Trick	Place a rubber band between the screw and hex key to improve grip.	Lightly stripped screws.
Pliers	Grip the screw head with locking pliers and twist.	Screws with exposed heads.
Screw Extractor	Drill into the screw and use extractor bit to back it out.	Severely stripped screws.
Hammer & Flathead	Tap a flathead screwdriver into the stripped socket to create grip.	Medium-level stripping.
Heat	Apply heat with a soldering iron to loosen threads.	Screws stuck by rust.

Step-by-Step: The Rubber Band Fix

1. Place a wide rubber band flat across the stripped Allen screw.

2. Insert the Allen key directly into the screw head.

3. Press down firmly and turn slowly.

4. The rubber band fills the stripped grooves, adding friction.

“This simple trick saves hours of frustration—always try it first before drilling or using extractors.”

When to Call a Professional

If the screw is embedded in valuable materials (like hardwood floors or plumbing fixtures), it may be worth hiring a pro to avoid costly damage. For example, dealing with problems with pavers over concrete is similar—you want precision and the right tools for the job.

Preventing Stripped Screws

• Always use high-quality Allen keys.

• Match the tool size exactly.

• Keep tools and screw heads clean.

• Apply steady pressure instead of jerking the tool.
