Fastener Arrangement with Compressible Washer

摘要

A washer includes a domed central portion with a central opening establishing a longitudinal axis, a base wall extending in a direction radially outwardly from the axis, and an extension wall extending in a direction radially outwardly and axially away from the base wall. The washer also includes a curled radially outer periphery with a peripheral wall extending radially outwardly from the extension wall and in a direction axially away from the extension wall back toward the base wall. A fastener assembly includes the washer and a fastener having a shank extending through the central opening of the central portion. A fastener arrangement includes the fastener assembly and an object to which the fastener assembly is fastened. A product, and a related method, include a panel carried by an underlying support structure to which the shank of the fastener assembly is coupled, with the curled radially outer periphery engaging the panel.

1. A fastener arrangement that includes:
a threaded fastener having a head with an undersurface, and a washer disposed adjacent to the undersurface, and having a domed central portion that is outwardly convex facing the undersurface, a center opening in the central portion, and a curled periphery that is outwardly concave adjacent to a periphery of the undersurface, such that threaded tightening of the head against an underlying support structure collapses the central portion and curls the periphery of the washer around the periphery of the head.
