About This Product

If you've ever tried to screw a nut onto a bolt with chewed-up threads, you know the frustration.
This CTA Tools thread restoring file is a lifesaver.

It's precision-crafted for SAE threads, with a crosscut design that matches the thread pitch depth so you don't skip or jump out of fine threads.

The file is 7/16-inch square by 8-3/8 inches long, and it covers a ton of common TPI sizes: 1, 12, 13, 14, 16, 18, 20, and 24 threads per inch.

That's most of what you'll run into on cars, tractors, or shop equipment.

The heavy-duty construction means it's strong and durable—it'll last through plenty of jobs.

Whether you're restoring a classic Corvette or doing maintenance on a John Deere, this file lets you clean up damaged bolt threads quickly and easily.

Just work it back and forth over the damaged area, and it restores the threads so nuts spin on smooth again.

Simple tool, big payoff.

No more cursing at stripped bolts or replacing perfectly good hardware just because the threads are a little banged up.
