Multipurpose fixing bolt

摘要

A bolt (1) with a head (2) and a thread (3) has a smaller diameter tip extension (19) with a circular recess (18) around the circumference. A small e.g. plastics plug (4) is push-fitted to the tip extension, and has a number of inclined tabs (5) inclined towards the bolt head and extending beyond the diameter of the thread (3). The bolt with tip plug is inserted through a bolt hole and secured by the nut (6) which is fitted over the tabs (5).
