A bolt is fabricated from an elongated threaded rod by severing the rod along a planar surface angularly oriented with respect to a longitudinal axial plane through the rod. A cup-shaped nut has three equicircumferentially spaced lateral locking openings in the side walls adjacent the outer base wall thereof. The cup-shaped nut has an axial length greater than twice the diameter of the opening, with the opening in the half of the nut including the base wall. The nut is threaded onto the severed end of the rod with the base wall abutting the end of the rod. At least one locking opening is exposed to the inclined planar surface, and a pin is forced into the exposed opening with the inner end of the pin terminating within the nut and located immediately adjacent to the inclined surface thereby affecting a positive interconnection of the nut to the rod. In one embodiment the pin is a solid pin formed of a softer metal than the rod. The opening in the nut is located adjacent the lower portion of the inclined plane. The nut is driven into abutting and complementary engagement with the inclined plane.
