High strength grip wrenches manufactured from rolled chrome vanadium steel with serrated drop forged hardened steel jaws for a positive high strength grip. The body of the grip wrench is coated with a corrosion resistant bright nickel finish and the jaw opening and clamping pressure can be adjusted as required turning the knurled head screw adjuster. Each wrench is fitted with a wire spring to ensure efficient jaw opening. The locking mechanism holds the wrench in place once adjusted, leaving both hands free!
