Title: Screw fastener
Inventor: TERAO TAKAHIRO
IPC: F16B39/30
Filed: 2019-06-14
Abstract: To provide a screw fastener that is hard to loosen as compared with conventional screws, and rich in flexibility.SOLUTION: A pair of recessed grooves 8a, 8b along a spiral line are formed in parallel between a mountain-side part and a valley-side part of a pressure-side flank 7 of a fastening bolt 1, and the part between the pair of recessed grooves 8a, 8b are in a flat shape. With this constitution, pressure-side flanks 7, 14 of a male screw 4 and a female screw 13 are not in contact with each other at sites of the recessed grooves 8a, 8b in a fastened state, so that the stress concentrating on the sites is dispersed to equally load flat parts 9a, 9b other than the recessed groove parts 8a, 8b. Consequently, screw threads become hard to plastically deform and harder to loosen than the conventional constitution.SELECTED DRAWING: Figure 4
