Crescent Nicholson T33001 No 1 Regular Bolt Thread Restoring File

The Crescent Nicholson T33001 No. 1 Regular Bolt Thread Restoring File is a practical tool for bringing worn or damaged external threads back to usable condition. Manufactured in the U.S.A., this square-profile thread file is built for use on bolts, rods, and pipes, making it a go-to solution for maintenance, repair, and fabrication work. With the ability to restore threads in 8 different TPI (threads per inch)—including 11, 12, 13, 14, 16, 18, and 24—this file eliminates the need to carry multiple tools for different thread sizes.

The 8-1/2″ length offers enough control for precision work without being bulky, and the carbon steel construction ensures long-term durability even under frequent use. Designed for external threads only, this file works best when applied directly to the damaged area by aligning the correct TPI edge and following the existing thread pattern. Each file is easily identified by a black color cap and comes packaged for straightforward storage and selection on busy job sites.
