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.

CM,1. A pre-assembled fastener and washer unit comprising a fastener having a shank with threads on a portion thereof and a head at one end said head having an upper and a lower surface, said shank having threads with a first predetermined lateral dimension and, an unthreaded region situated between the threads and side head, a first annular protrusion having a second predetermined lateral dimension greater than the first extending outwardly from said unthreaded shank region, a second annular protrusion having a third predetermined lateral dimension also greater than said first extending outwardly from said unthreaded shank, said second protrusion being spaced farther from the fastener head than said first protrusion, a washer member having an upper and lower surface and a hole passing generally axially therethrough the periphery of the hole having a fourth predetermined lateral dimension which is greater than the first but less than the second and third such that the washer, when assembled with the fastener by passing the periphery of the washer over the threads and forcing the washer over said second protrusion, will be retained between said first and second protrusions at a position spaced from the lower surface of the head so that the upper and lower surfaces of the fastener head and washer will be accessible for painting and the like.
