Knurled screws GN 464.2 are used, for example, to fasten machine covers. The shank d4 provides simple loss prevention. Instead of a through-hole, this requires a second thread d1, 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.
