ABSTRACT:
A threaded fastener has a pin with a head, a cylindrical shank, a shoulder with reducing diameter, a radius at the least diameter of the shoulder whose region is work-hardened, and a threaded end, in that order. The thread extends into near-adjacency to the shoulder, and has no more than approximately one-half of a convolution of an incomplete thread at its end adjacent to the shoulder. A collar is threadable onto the thread. It has a counterbore no longer than the anticipated grip range plus approximately one-half of a thread pitch. The collar may be inherently torque-limited. The term "thread" also includes a peripheral groove.
