Lang Tools Thread Restorer Files

Lang Tools thread restorer files renew damaged external threads, of any diameter, right or left hand. Just select the proper number of threads per inch or millimeters per thread; then, overlapping several good threads, work over the area using regular file strokes.

Sold individually or in sets with a reusable pouch, they can restore SAE thread pitches from as few as nine up to 32 threads per inch. Metric thread files can renew a range of pitches from 0.75mm through 3.00mm per thread. Rethreading files are highly tempered for strength and durability.
