Special nuts with screw lock

HELICOIL® locknuts are one-piece fasteners because the nut is connected to the HELICOIL® screwlock thread insert.

Characteristics

Locking of the screw is achieved by one or several polygonal-shaped threads on the HELICOIL®. These threads clamp the flanks of the screwed-in screw; the result is an elastically resilient frictional locking. The achieved locking torques can be compared to the indications in ISO 2320.
