Fastening system for threaded bolt in through-bore - uses stamp action of inserted bolt head to engage on ring face of flat section

摘要

The ring end face supported axially on the flat profiled section has several tooth-like protrusions (13) evenly spread out over the end face in a radial extension. The bolt head (9) can be pressed into the associated end area of a full-length bore matching the dia. of the threaded bolt (8) and sinks into the matching indentation through the teeth (13) as the flat section compresses. The bolt head is thereby secured through a positive locking engagement. The flat section can be made from light metal and the bolt head from steel. USE/ADVANTAGE - The bolt head sits securely sunk in the flat section irrespective of the measurements of the bore.
