A cover nut and bolt assembly comprising:

• (a) a work piece having a generally flat surface;
• (b) an externally threaded bolt having an end portion protruding outwardly along an axis from said flat surface;
• (c) a symmetrical nut threadedly received on said end portion of said bolt, said nut having circumferentially a plurality of equally spaced flat side surfaces and equally spaced straight and continuous points forming common edges of the side surfaces of said nut at the maximum diameter of said nut, said points extending axially throughout substantially the entire length of said sides, said sides being flat throughout substantially their entire lengths;
• (d) A cover or cap having a hollow tubular body, the interior of which has an inside dimension slightly larger than the maximum diameter of said nut, the cap or cover having an end portion which surrounds said nut when said cover or cap is placed over said nut and said end portion of said bolt, and a plate completely closing the other end portion of said body;
• the interior of said body being essentially unobstructed between the end of the bolt and the plate and being of a length greater than the length of either said end portion of said bolt or said nut, said body at said one end portion of said body having an end surface for abutting said flat surface when said cap or cover is inserted over said nut;
• (e) said body being provided with a radially disposed continuous groove along said inside surface;
• and
• (f) an elastomeric member received in said groove for frictionally firmly engaging said points of said nut when said cover or cap is inserted over said nut and said end portion of said bolt for providing essentially the sole means for securing said cap or cover in place on said nut.
