Knurled screws GN 653.2 can be used for to prevent loss of the thumb screw, due to the d4 recessed portion of the stud.
When using, instead of a typical tapped and bore hole, it is necessary to provide tapped bores with a thread d1 on each of the two elements to be assembled. Additionally, a clearance bore of d5 on one or both sides must be cut.
Depending on the design and required clamping length a1 ... a3 of the component being attached, there are a number of assembly options as shown.
