GN 653.2 Flat Knurled Thumb Screws Steel, with Recessed Stud for Loss Protection

Photo

Product description

Information

GN 653.2 flat knurled thumb screws can be used to prevent loss of the screw due to the d4 recessed portion of the stud.

When using, instead of a typical tapped and bored 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 above.
