2 Pcs 1/2 Drive by 27mm Shallow Impact Socket Cr-Mo Alloy Steel 6-Point Metric

* Made of high-grade Chrome-Moly steel for strengthen and durable to use. * To protect against rust and corrosion the black phosphate finish absorbs and holds oil repelling moisture. * Has 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. * 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. * Widely used in DIY hand-making household maintenance and most general repairs.
