Böllhoff 64 piece M2.5 x 0.45 Thread Repair Kit

Metric ISO thread repair kit.
These kits contain 10 threaded inserts, a drill bit (up to M12), a precision tap, an HSS tap, a fitting tool (up to M12), all supplied in one case.
Ideal in situations where a thread has been stripped and there is no plan to increase the diameter of the screw.
A simple repair is made by fitting a HELICOIL insert using the tool provided and a tap wrench or other tool used to create standard threads.
