SKT 1/2DR HI STR MAG IMP9/16

Allows room for more magnet material, helping increase total magnetic strength. Designed to easily pick up heavy fasteners and hold them tightly during use. Impact sockets with high-impact strength are used in automated and hand impact socket application. ProtoGrip™ magnetic sockets require no bushings to hold the magnet in place. The sockets use high strength magnets made from a rare earth magnet alloy/nylon blend.
