A stud fastening assembly (10) including a stud (11) having a threaded end threadable into a hole (15) formed in a workpiece (16) and a plurality of serrated rings (21) and (22) for securing the stud in place. The serrated rings include inner serrations (20) sized to slodably engage longitudinal serrations (14) formed on a mid-section of the stud and further include outer serrations (19) configured to engage the sidewalls of the hole formed in the workpiece and thereby prevent relative rotation. The lower ring includes fewer outer serrations than does the upper ring, to facilitate installation. |
