Abstract:
To design a threaded fastener in which load dispersion between screw threads is improved.
The fastener (10) includes a threaded surface (12) with a predetermined effective diameter (26). The effective diameter (26) of the threaded surface (12) is configured to be changed along a first section of the threaded surface (12). The effective diameter (26) of the threaded surface (12) is further configured to be changed along a second section positioned on a side opposite to the first section.
