Product description

Knurled screws EN 591.2 are used to fasten machine covers, for example. The shank d4 provides simple loss prevention. Instead of a through-hole, this requires a second thread d2, potentially with a corresponding clearance bore d5.

Depending on the design and required clamping thickness a1 ... a3 of the cover, there are a number of assembly options as shown.
