How to Fix Stripped Screws, Broken Bolts, and Stuck Fasteners

Every DIYer runs into this problem eventually. A screw won’t turn. A bolt snaps. The head strips out just as you’re about to finish the job.

It’s frustrating — but it’s also completely fixable.

The key is knowing which method to use, and when. Because with the right approach (and a few tools you’ll find on Tools4), even the most stubborn fastener can usually be removed without damaging your project.

Let’s break it down.

Start Simple (Before You Reach for Special Tools)

Not every stuck screw needs a complicated solution.

Sometimes, all you need is more grip.

Try this first:

• Press your screwdriver firmly into the head
• Add a rubber band or steel wool for extra friction
• Tap the screwdriver lightly with a hammer to seat it deeper

These simple tricks increase contact and can often free slightly stripped screws without much effort

If the screw is slightly exposed, locking pliers can also give you enough grip to twist it out.

Extraction Tools (The Proper Fix)

When basic methods fail, it’s time for the right tool.

Screw extractors are designed specifically for this job — and they work extremely well when used correctly.

Here’s how they work:

1. Drill a small pilot hole into the damaged screw
2. Insert the extractor
3. Turn it counterclockwise
4. Let it bite and pull the screw out

These tools are designed to grip tighter as you turn, making them one of the most reliable solutions for stripped or broken fasteners

You’ll find full extractor sets on Tools4, often bundled with drill bits, making them a smart addition to any workshop.

For rounded bolts, bolt extractor sockets are even easier — they grip the outside of the bolt and remove it without drilling.

Penetrating Oil (The First Step for Rusted Fasteners)

If rust is involved, force alone usually won’t work.

This is where penetrating oil comes in.

Spray it onto the fastener and give it time to work — usually around 15 to 30 minutes. The oil seeps into the threads, breaking down rust and reducing friction

For stubborn cases, repeat the process.

Many DIYers skip this step and go straight to brute force — which often leads to stripped heads or snapped bolts.

Patience here saves a lot of effort later.

Heat: The Trick Most People Don’t Use

When a fastener is completely seized, heat can make a big difference.

Applying heat causes the metal to expand slightly. When it cools, it contracts — breaking the bond between the threads.

A heat gun (available from Tools4) is usually enough for most DIY applications.

The process is simple:

• Apply heat for a few seconds
• Let it cool (or apply a little penetrating oil)
• Try loosening the fastener again

This expansion and contraction cycle helps break rust and corrosion bonds, making removal much easier

When Things Get Really Stuck

If the head is completely stripped or broken off, you still have options.

You can:

• Drill a clean pilot hole and use an extractor
• Cut a new slot into the screw head using a rotary tool
• Use a left-handed drill bit (which can sometimes reverse the screw out)

These methods take a bit more care — but they’re often the difference between saving and scrapping a project.

Common Mistakes That Make It Worse

Most stripped screws don’t start that way — they become that way.

Here’s what usually causes the problem:

• Using the wrong size screwdriver
• Applying too much force too quickly
• Skipping lubrication on rusted fasteners
• Rushing the removal process

Once a screw strips or snaps, the job becomes much harder.

The Real Secret: Slow Down and Use the Right Method

Fixing stuck fasteners isn’t about strength.

It’s about control, patience, and choosing the right approach.

Start simple. Add grip. Use oil. Apply heat. Then move to extraction tools if needed.

Because in most cases, the difference between a nightmare job and an easy fix comes down to one thing:

Using the right method at the right time.

And once you’ve done it a few times, it stops feeling like a problem — and starts feeling like just another part of the process.
