ABSTRACT:
The stud retention device has a top end, a base defining a bottom end and two diametrically opposed longitudinal members defining a shank. The shank has a longitudinal passage in which a ribbed stud or externally threaded bolt is insertable. Staggered along the length of the shank are one or more ribs, each rib having a finger projecting inwardly. One or more flexible arms project from the base toward the top end, where the angle between each arm and the shank is 45 degrees. When a stud or bolt is inserted into the passage, arms and fingers engage in the recesses between the ribs of the stud or threads of the bolt, thereby imparting a retention force which prevents retraction of the stud or bolt from the passage. A range of stud diameters and lengths may be coupled with the stud retention device.
