Information

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.
