Kastar Hand Tools 972 40-PC. SAE & Metric Thread Restorer Kit

[TT]

Kastar has come out with a kit that just about every technician should have on hand. Not a tap & die set, this is a thread restorer and thread cleaning kit. A must have for anyone who is working with questionable threads on motors, vehicles bodies, equipment and more. Doesn't take material away (cut) threads like a tap and die, just realigns the existing metal back to the shape it was originally cut in - this maintains the fasteners strength. Great for cleaning out rust/oxidation and threadlocker from critical parts.
