SOCKETS

Proto Tools is an American industrial hand tool company. Founded as Plomb, it is presently a division of Stanley Black & Decker. The company is credited with creating the first combination wrench in 1933. ProtoGrip™ Magnetic Sockets use high-strength magnets made from a rare earth magnet alloy/nylon blend. ProtoGrip™ Magnetic Sockets require no bushings to hold the magnet in place. This allows room for more magnet material, helping increase total magnetic strength. Designed to easily pick up heavy fasteners and hold them tightly during use.
