Threaded insert Application Threaded insert Ensat®-SK 302 1 with cutting slot and head is a self-tapping fastener for the creation of wear-free, vibrationresistant screw joints with high loading capacity in materials with low shearing strength. Head, the pull-through force is. The head serves as a support for electrical contacts when fastening several parts simultaneously; when stress is applied against the head, the pull-through force is significantly increased. It is suitable for installation in the following materials: – Light alloys – Cast iron, brass, bronze, NF metals – Plastics, laminates – Hardwoods Article number External thread Head diameter Head height Guideline values Minimum for receiving borehole depth hole diameter for blind holes L 6,1 to 6,2 7,5 to 7,6 9,2 to 9,4 11,2 to 11,4 13,2 to 13,4 Example for finding the article number Self-tapping threaded insert Ensat®-SK to Works Standard 302 1 with internal thread A = M5 made of case-hardened, zinc plated and blue passivated steel: Ensat®-SK 302 100 050.110 Case-hardened steel, zinc plated, blue passivated Case-hardened steel, zinc-nickel plated, transparent passivated Stainless steel 1.4305 Brass Article no.
