Helicoil Insert, 1/2"-13 (Bulk)

Helicoil Insert, 1/2"-13

The 1/2 in-13 Helicoil Thread Insert is designed to repair or reinforce damaged threads in metal components, restoring the original 1/2-13 UNC thread size. Made from high-strength stainless steel wire formed into a precision coil, this insert creates durable internal threads that often exceed the strength of the original tapped hole. Helicoil inserts are widely used in machinery, automotive repair, and equipment maintenance where stripped or worn threads need a reliable permanent fix—because replacing an entire part just for damaged threads is rarely the favorite option.
