Thread Chasing Tap Set

Be the first to review this product



Thread chasers are used to ensure threaded holes are free of burrs or previously applied thread locking agents so proper torque is applied during re-assembly. Unlike thread cutting taps, chasers do not remove parent material from the threaded holes. Set of 6, sizes 1/4-20, 5/16-18, 3/8-16, 7/16-14, 1/2-13, 9/16-12.
