Fastener and washer assembly

摘要

An assembly of an internally threaded fastener (12) and a stemmed washer (14) is provided, such as for applications in which a standoff is desired between a washer (22) and a mating externally threaded fastener (46). The stemmed washer (14) includes a washer portion (22), a retaining portion (26) and a standoff portion (24). The retaining portion (26) interfaces with a skirt (20) of the internally threaded fastener (12) to retain the fastener (12) in the assembly. The stemmed washer (14) may include a skirt (26) which is plastically deformed to capture the fastener (12). Alternatively the fastener (12) may include a skirt (62) which is similarly plastically deformed to mate with a retaining lip (64) on the stemmed washer (14). The fastener (12) and washer (14) are preferably secured in the assembly to permit relative rotation of the fastener (12) with respect to the washer (14). <IMAGE>
