Bought that same vise a year ago and when rec'd, the moveable jaw wouldn';t move ....too much clearance between the screw and nut. They sent me a replacement and it's mounted on my bench but it's a lousy vise. Takes 3 turns of the screw to start the moveable jaw to clamp. Tried all sorts of adjustments and it still won't clamp w/o the part slipping. Don't like to " badmouth" a product, but this vise deserves it......Fred
