Thus the „captivity of the mounting element“ according to the Machinery Directive 2006 / 42 / EG is given. When using, instead of a typical tapped and bore hole, it is necessary to provide tapped bores with a thread d 1 on each of the two elements to be assembled. Additionally, a clearance bore of d 4 on one or both si- des must be cut. Depending on the design and required clamping length a 1 ... a 3 of the component being attached, there are a number of assembly options as shown above. see also... • Knurled Screws GN 653.2 (with a Thin Shank for Loss Prevention) → Page 651 Information 1 d 1 2 l 1 3 Material How to order 1 2 3 GN912.2-M6-30-NI • Stainless steel AISI 304 NI • Stainless Steel Characteristics → Page 2166 • RoHS Specification 3 GN 912.2 Stainless Steel Captive Socket Cap Screws with Recessed Stud for Loss Protection
