Abstract

See full text

A pre-assembled fastener and washer which facilitates application of paint to surfaces that would otherwise be exposed. Two annular protrusions formed on the unthreaded shank adjacent the head serve to retain the washer and fastener in an assembled condition with the washer spaced from the fastener head. Once the assembly has been painted and dried, the washer can be moved to its fully assembled position adjacent the fastener head. A method of forming a painted assembly is also disclosed.
