Abstract
The subject invention is a master link which comprises a heavy duty roller chain with end hooks and safety pins on each end of the chain. The master link is used in combination with a rotatable chuck, having a head with at least three jaws mounted thereon for radial movement, to hold the jaws in place during remachining operations. The chain is made into a circle with the end hooks engaging rollers of the chain to define a circle of specific size so that when it is applied around the jaws of the chuck, the master link restrains the outward movement of these jaws.
