You’re staring at a stripped thread on a prized engine block—every turn of the wrench risks costlier damage and downtime.

Left unfixed, the part loosens under vibration, leaks surface, and a full replacement looms—draining your wallet and your weekend.

Bostome 338 delivers the authority of a professional shop in one Piece Helicoil set. HRC 55–62 drill bits and 304 stainless inserts restore M5–M12 and ¼"–½" threads in minutes, not hours. The rubber-grip tang-breaker seats coils cleanly; the rugged case keeps 338 precision components organized between jobs. Drill, tap, insert—done.
