Reliable Helicoil Thread Inserts for Lasting Thread Strength
Engineered for thread reinforcement and repair, heli coil and heli coils thread inserts deliver precision‑formed, wear‑resistant threads that extend the life of softer metals like aluminum or magnesium. They provide lasting performance where lightweight materials need additional holding strength and reliability.
Unlike solid or key‑locking inserts, heli coils offer flexibility in installation and are ideal for restoring stripped threads without adding significant weight or material thickness. Combined with Fastener Tool & Supply’s range of threaded inserts and repair kits, they help manufacturers maintain quality control and reduce rework across assembly operations.
