No longer manufactured, Di-Lok chain is a forged alloy steel stud link chain with an integral stud with superior strength to weight. Each link is composed of two forged members: a serrated stem member and a socketed member. A cold heat treated serrated member is placed into the hot socketed member and assembled by forging in closed dies.
The unique design of Di-Lok stud link chain allows the use of various alloy steels and heat treatments. The integral stud is formed in the forging of the socketed member and cannot be dislodged. With modification in die design, high strength and super strength Di-Lok chain was manufactured to obtain superior test loads.
