The Yost BV-6 6" bench vise is an all-purpose bench vise. A staple for any home workshop, no matter what your job is. Built for durability and dependability, this vise is constructed from 30, 000 PSI cast iron. The replaceable serrated jaws will prevent objects from moving around once you have clamped them in place. A large anvil on the back of the vise is perfect for forming and shaping metal pieces. The anvil is machined to provide a smooth work surface. The 120 degree swivel base allows this vise to be positioned in to clamp parts with ease. The dual lockdowns on the vise are designed to keep the vise in place once in position. The acme threaded main screw provides smooth operation.
