Overview:
The Volkel M12 x 1.75 Thread Repair Kit (MPN 04021) is a practical set for restoring damaged internal threads or creating durable new threads in metal components. It is designed for workshop, site, and garage use on construction and garden machinery, engines, gearboxes, fixtures, and general fabrications. The kit supplies a matching drill, an STI (screw thread insert) tap, and 10 wire thread inserts, giving you the essentials to prepare, cut, and reinforce an M12 coarse thread. By installing a wire insert into a correctly sized and tapped hole, you regain full-strength threads that are resistant to wear and stripping. Suitable for repairs in common metals used in housings and castings, it helps extend the service life of parts without replacing costly components.
