Browse a selection of impact wrench sockets and impact driver sockets from Grainger. Sturdy impact sockets can be used to tighten or loosen high-strength fasteners that require more torque than standard fasteners. Sockets use heat-treated alloy for extra strength and black oxide or black sulfate for corrosion resistance. Impact drivers feature a heavy-duty spring for added torque. We've also got a robust lineup of impact socket accessories including impact universal joints, socket retaining rings, and retaining pins.
