Fastening in high-temperature applications
HELICOIL® nuts with integrated HELICOIL® Screwlock ensure locked screw joints, even at high temperatures.
Prevents self-loosening. The threads of the HELICOIL® Screwlock clamp the flanks of the screw or bolt to be inserted – for an elastically resilient frictional locking and optimal screw locking.
The locknut retains its strength even at high working temperatures (e.g. in exhaust systems). Seizing is also prevented.
High-strength nuts in combination with HELICOIL® Screwlock thread inserts – optionally with washer. No loosening on loss of preload force due to the use of seals. For greater security.
Method and principle
The locknut consists of a nut body and the coil thread insert HELICOIL® Screwlock. Screw locking is achieved by the polygonal threads on the HELICOIL® Screwlock. These threads clamp the flanks of the screw or bolt to be inserted. The result is an elastically resilient frictional locking and hence screw locking to prevent self-loosening. Depending on the application, multiple polygonal threads can be used to achieve increased clamping torques.
