Abstract
A nut and tail assembly (10) and method of manufacture including a nut (12) having a first end and an inward flange (24) at the other end, a longitudinal cylindrical hollow body (14) having a first end and a second end at which is located an outstanding flange (40) and a circular longitudinal sleeve (16). The sleeve (16) extends along said sliding surface and has a flange (44) at a first end abutting against the body flange (24). A stop (34) is located between the ends of the body (14) and defines a cavity sliding surface generally parallel to the longitudinal body between the stop (34) and flange (44). The nut inward flange (24) extends into the body cavity and is of a large enough diameter to be able to slide on said body sliding surface but small enough to be held within said cavity defined between said stop (34) and sleeve flange (44). Projections (50) on the sleeve flange (44) assist in locating the sleeve (16) relative to the nut (12) during the moulding process.
