TORSION COTTER PIN AND METHOD OF USE

摘要

A torsional fastening assembly provides a pin that leverages torque from a torsion spring and a pair of deviated free ends to fix a slotted nut in a locked threaded position. The pin includes a torsion spring that diverges into a pair of legs having free ends. A first free end includes a hump, while a second free end includes a generally 90° bend. The torsion spring exerts a torsional force on the pin that biases the pair of legs to diverge. The legs pass through a slotted nut and a threaded bolt. The hump and the generally 90° bend are engaged around the respective threads of the slotted nut and the bolt, such that the slotted nut is restricted from rotating relative to the bolt. The pin is fabricated from stainless steel to enhance tensile strength and inhibit rust. A cap conceals the pin and the slotted nut.

1. A torsional fastening assembly, the assembly comprising:
a pin, the pin defined by a torsion spring, the torsion spring configured to exert a torsional force in an opposite direction in which the torsion spring is wound, the pin further defined by a pair of spaced apart legs terminating at a first free end and a second free end, the first free end having a hump, the second free end having a generally 90 degree bend, wherein the torsional force biases the pair of legs to diverge at the free ends.
