Features & Benefits

Knurled nuts and screws can be easily tightened and loosened by hand. The ribbed outer surface ensures a firm grip and prevents slipping during operation.

The thread is manufactured up to the head with runout and without undercut at the end (DIN designation A).
Due to this design, the screws cannot be fully tightened up to the head.
