Knurled Thumb Screws GN 653.2

Product description

Information

Knurled thumb screws GN 653.2 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.
