Description
Welded end links are manufactured in conjunction with welded stud-link chain from alloy-steel bar stock. However, to compensate for the loss of strength due to the absence of the forged stud, they are of a larger wire diameter than the chain with which they are manufactured. Normalizing of the entire chain length ensures the same physical strength throughout. Installed at one or both ends of the chain length, the studless end link enables shackles to be joined directly to the chain — a procedure normally prevented by the presence of a stud.
