Proto J7416PF 1/2 Drive High Strength Magnetic Power Socket 1/2 - 6 Point

ProtoGripâ„¢ Magnetic Sockets use high-strength magnets made from a rare earth magnet alloy/nylon blend.ProtoGripâ„¢ 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.Strong magnetic hold helps increase efficiency when installing fasteners in awkward or hard-to-reach locations.Power sockets with high surface hardness are used in high-speed assembly operations. Ideal for nut runners.
