Pem® S-RT® – free-running locknut
This PEM fastener has a specially designed self-locking thread, in which the connecting screw can be driven through with free hand operation and without resistance during installation. When the screw is tightened, the thread design creates a self-locking effect, which protects the joint against loosening. Even after the screw is loosened, it can be screwed in the nut with free hand and can be tightened/loosened again. Self-locking is achieved each time the bolt is tightened.
In terms of size, it is available in threads from M3 to M8. Type S-RT is made of zinc plated hardened carbon steel and can be pressed into plate up to HRB 80 (HB 150) hardness.
