HELI COIL (75085)

HELI COIL (75085)

Helicoil is a threaded sleeve , with an overall structure resembling a spring. Its design concept is to insert a coil of metal wire into a damaged or slipped-threaded hole, thereby creating a new set of threads within the original hole. Due to the use of a rhombic cross-section metal wire, Helicoil can achieve a larger contact area and locking force within a limited space, resulting in a repaired thread strength often exceeding the original base material.
