Fastening in high-temperature applications
An efficient and reliable linking of two fasteners
HELICOIL® nuts with integrated HELICOIL® Screwlock ensure locked screw joints, even at high temperatures.
Plus factors
Advantages of HELICOIL® locknuts
Screw locking
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.
Temperature-resistance
The locknut retains its strength even at high working temperatures (e.g. in exhaust systems). Seizing is also prevented.
Modularity
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
Secure even at high temperatures
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.
