摘要

The fastening element has threaded passages (4) extending up from the base (5) and provided in the attachment area for the screw with a centring aid (7,8) such as a collar-like expansion (7). On one side this adjoins the thread (6) and on the other is provided on the inlet side with an inlet radius (8). The collar like expansion (7) can be moulded at the same time as producing the threaded passage. The fastening plate can be made from sheet metal or aluminium. ADVANTAGE - Easier manufacture without the need for stock-removing work.
