Weight screw

摘要

A screw comprising a drive part, a threaded part, and a retaining ring is disclosed herein. Each of the drive part and the threaded part comprises a plurality of interface surfaces that transmit torque from the drive part to the threaded part and prevent the parts from disengaging from one another during use. Each plurality of interface surfaces forms one or more geometric shapes that create additional friction between the drive and threaded parts, and may further include mating pins and holes to prevent the parts from detaching from one another. The retaining ring, which removably connects the screw to a wrench during assembly of the screw with a receptacle, is disposed within a cavity formed when the drive part is assembled with the threaded part.
