Knurled screws 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.
Stainless Steel-Hexagon head screws GN 933.5 with brass or plastic pivots are used when pressure dents or damage to the clamping surface must be avoided. Stainless Steel-Hexagon head screws GN 933.5, type ZK, feature a spherical pivot whose diameter d4 is smaller than the core diameter d1 of the thread. This makes them suitable for holding thrust pads GN 631 GN 631.5 which must be ordered separately.
