Abstract: A screw mounting clip member is adapted to be slidably fixedly engaged in a slotted aperture adjacent an unthreaded screw-receiving borehole. A spring detent member provided on the clip extends into the borehole when the clip is fixedly mounted in place. A threaded screw is fastened in the borehole by initially being manually thrust endwise into the borehole without turning, thereby deflecting and forcefully engaging the spring detent with the screw threads. The screw may thereafter be tightened by turning the screw against the spring detent and may be unfastened only by reverse turning of the screw, in the conventional manner.

Abstract: An improved locknut has a hexoganal body with a threaded central opening. The threaded central opening has noncircular lock thread convolutions with a reduced pitch. Standard thread convolutions are disposed adjacent to the bottom of the opening to facilitate engagement with the mating thread. To form the lock thread convolutions, a hexagonal nut is moved through a nip between a pair of rotating externally toothed indenting wheels. As the nut passes through this nip, crest portions of the teeth on the indenting wheels move into engagement with opposite flat side surfaces of the nut body. As the nut body continues to move through the nip, the externally toothed wheels indent the nut body at spaced-apart locations. To promote accurate control of the axial extent of the lock thread convolutions, the external teeth on the indenting wheels have a tooth depth which is greater than the depth of the indentations formed in the opposite sides of the nut.
