SAPER LOCK® locknut
Clamping effect directly in the thread – elastically resilient Even clamping torque in repeated screwings Constant thread friction Uniform load
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.
