US 2022/0389952 A1 · BOLT RETENTION DEVICE

Abstract

A bolt retention device is provided that includes a bolt having a shaft, a retention portion that includes a radial retention surface extending along the shaft, a sleeve having a cylindrical base with an inner bore, and at least one rib extending radially from the cylindrical base, wherein the retention portion has a diameter sized to receive the inner bore of the sleeve, and wherein the bolt is inserted into the sleeve to align the retention portion with the inner bore of the sleeve. The sleeve works to retain the bolt in a coupling aperture by applying a resistive force in the direction opposite the direction of motion. This resistive force is caused by physical interference created by the ribs against the inner bore of the coupling aperture. The ribs may vary in shape to create different desirable resistive characteristics.
