Riveting kit inserted in hole

摘要

The kit has a sleeve (110) which forms part of a body (100). Flanges (122) protrude from one side of it. These have inwardly protruding parts. A triangular hole (106) extends through the body and sleeve and also part-way through the flanges. It has flat surfaces on the inside of the latter. A pin (200) with a triangular-section stem (220) engaged with the inside surfaces of the inwards-protruding portions of the flanges has a pyramidal tip (210) at one end tapering from the stem, and a head (230) at the other. The tip aligns the stem with the triangular hole when inserted in it. On thrusting further home, the flanges are thrust outwards.
