Abstract
A screw-latching assembly is provided. The assembly includes a screw with a head, a tip, and a body between the head and tip. The body includes a threaded portion adjacent to the tip and an unthreaded portion adjacent to the head, and the unthreaded portion includes a built-in collar with an outer diameter larger than that of the body. The assembly includes a supporting bracket supporting and partially encompassing a first portion of the screw. The supporting bracket includes a base and multiple sidewalls, with a first sidewall comprising a first opening to allow a second portion of the screw to extend out of the supporting bracket and a second sidewall comprising a second opening to allow access to the head by a torquing tool. The assembly includes a spring surrounding at least a portion of the body, with the spring positioned between the built-in collar and the first sidewall.
