Abstract

A resilient seal 15 for the head 14 of a headed pin fastener member comprises an annular sealing bead 25, an annular boss 24 projecting on both sides beyond the thickness of the bead 25 and having tapered faces 29, 29, and a thin annular web 26 joining the parts 24 and 25. The symmetry of the seal enables it to be assembled on the pin either way round, with the same result.
