Helical Wire Thread Inserts

APPROVED VENDOR, HELI-COIL

Free-running and locking internal designs are different. Screw thread insert taps sold separately. Free-running inserts are greater in diameter than tapped hole; compress when installed. Inserts evenly distribute load and stress. Screw locking inserts eliminate backout of installed fastener from stress and vibration. Locking torque is retained over numerous assembly cycles.

Length is installed length.
