TEKTON 1/2 Inch Drive x 1/2 Inch 6-Point Impact Socket | 47751

The TEKTON 1/2 in. Drive x 1/2 in. Impact Socket is engineered for use with impact drivers. It has a 6-point opening that snugly fits the hex shape of fastener heads allowing it to apply maximum torque without slipping. To prevent round-off under stress it grips the flat sides of fastener heads rather than the corners. Easy to read even in low light the large high-contrast size marking is permanently laser etched into the steel surface. The through-hole in the drive end locks onto the tang of impact wrenches or drivers so it won t fall off or stick on fastener heads. To protect against rust and corrosion the black phosphate finish absorbs and holds oil repelling moisture.
