Ring-locked Studs

Used in mated pairs, Ring Locked Inserts and Studs are ideal for use in gear boxes, engines, pumps and vehicles in general. They provide excellent performance in high fatigue/high vibration applications. Their superior torsional resistance combined with a serrated Lockring, prevent the stud from backing out, in either soft or hard parent materials
