General description

The M8 lock nut made of A2 stainless steel is a self-locking nut with a serrated flange. The special serration on the contact surface allows the nut to grip firmly into the material and reliably prevents it from loosening due to vibrations or dynamic loads. Ideal for applications where a permanent and secure screw connection is required.
