Title: Stud hardware with self-contained stud anti-rotation feature and method of installing studs

Abstract

Disclosed herein is a method and apparatus for preventing the rotation of a stud member during preloading. The apparatus comprises a stud member having a shaft portion extending into the member to be clamped and a hex or double hex portion carrying a locking nut. Extending outward from the hex or double hex portion of the stud there is a threaded portion carrying a nut which is torqued to preload the stud. Between the locking nut and the member to be clamped is a locking ring which engages the locking nut to prevent the stud from rotating during preloading. Also disclosed is a method of preloading a stud without the use of an external restraint to prevent the stud from rotating when a torque is applied.
