Lily Z. ★★★★★

My neighbor's tractor had a bolt that was completely buggered from years of hard use, and this file made quick work of cleaning up the threads without removing too much metal. The 12-28 TPI range covered the medium-sized bolts I needed to fix, and it felt solid in my hand.

David ★★★★★

Rusty pipe threads on an old gate valve were beyond saving with a wire brush, but this file cut through the crud in a few passes and the threads engaged like new. The crosscut pattern really grabs hold without slipping, and the 12-28 TPI range covers most of what I work on around the house.

Elizabeth ★★★★★

I've used this file on a few bolts with chewed-up threads, and the 12-28 TPI range handled both fine and coarse threads without skipping. The cross-cut design bites into the metal evenly, so it doesn't just smooth over rust—it actually reshapes the thread. For the price, it's a solid tool to keep in
