What are HeliCoil Screw Locking Wire Inserts?
HeliCoil Screw Locking Threaded Wire Inserts are designed to create load-bearing joints in metal materials. When installed into a HeliCoil tapped hole, the threaded insert provides permanent conventional screw threads. These coils serve as a locking device by gripping the threads of the installed screw, effectively preventing the screw from loosening under vibration or impact. They permit frequent removal and reassembly of bolts without loss of torque.
What are HeliCoil Free Running Wire Inserts?
HeliCoil Free Running Wire Inserts include internal threads that are true to gauge and can be used from both ends. Every free-running thread of the thread insert is precision formed of extremely hard, diamond shaped stainless steel. Learn more by watching this video:
What are HeliCoil Tangless Inserts?
Tangless threaded inserts provide permanent, wear-resistant screw threads. They eliminate the need for tang retrieval and can be easily adjusted or removed after installation. No loose tangs are left behind from tangless inserts, so they’re ideal when foreign object debris cannot be present in critical applications.
We offer HeliCoil tangless inserts in both Screw-Locking and Free-Running styles. The “Free-Running” tangless inserts provide a smooth free-running thread, while “Screw-Locking” tangless inserts provide self-locking torque on the male member by a series of chords on one or more of the insert coils.
