Made in US. The Predator Grip Universal Socket is a universal wrench that instantly adjusts to just about anything you need to screw or unscrew! The super-tool sports a unique build with 54 hardened steel spring pins. When placed onto a fastener, some pins retract while the rest of the pins surround it and allow you to easily manipulate the piece. It fits virtually anything that isn't round: hex nuts and bolts, eyebolts, wing nuts, square nuts, broken nuts, hooks and more. Use around the home, on boats, RVs, cars, motorcycles and bikes. Just press it on and turn. It works great with power tools. It's the one tool that everyone can use. The socket contains 54 spring-biased hardened alloy steel rods. When placed over a fastener the center rods retract while the outer rods surround the fastener. As the fastener is turned the torque is transmitted through the outer rods to the walls of the socket. The 3/8"diameter delivers 100 ft. lbs. of torque and fits bolt heads up to 3/8" long. The 1.0" diameter can deliver more than 100 ft of torque. It works great on rusted fasteners and on bolts with damaged heads. The power drill adapter connects it to power drills and screwdrivers for high speed driving of nuts, lag bolts and more.
