An elongated nut holder has an elongated slot formed with a relatively narrow first entrance neck slot portion and a wider internal second slot portion. The second slot portion has a concave circular cylindrical segment bottom surface. A nut has an elongated body with a top flat surface and a bottom convex curved surface complementary to the second slot portion bottom surface curve. The nut has one or more threaded openings in the top surface which may be through holes. The nut has a transverse width greater than the neck slot portion transverse width and less than the slot second portion width so that the nut is retained in the second slot portion. The nut has a height less than the neck slot portion width. The nut has an edge between the top and bottom surfaces which is inserted first through the neck slot portion. The nut curved surface engages the nut holder curved surface which rotate the nut so that the nut flat surface and threaded opening(s) face the neck slot portion. A threaded fastener is attached to the nut threaded openings through the neck slot portion.
