#2 Fractional Thread Restoring File 9, 10, 12, 16, 20, 27, 28, & 32

Excellent tool for restoring threads. Just match the correct threadpattern - USS, SAE, Metric, and pipe. The file teeth will regrind and remove damaged threads so pipe fittings or externally threaded fasteners can be repaired.
For safety reasons and to prevent possible OSHA violations, a tanged file should never be used without a tight-fitting handle. A handle will not only help prevent accidents, it helps make the job easier and more enjoyable.
