The Irwin 1ZR is rigid and robust. The body and sliding jaw are cast from close grained grey iron which is machined on all friction surfaces for a smooth, reliable action. The jaws, handle and main screw are steel, the latter having a two-start rolled acme thread to speed the jaws from fully closed to fully open with a minimum of winding. The mechanics’ vice is the most commonly used vice in the record range. A full line of replacement parts are available.
