1/2 Drive 19mm 12-Point Deep Impact Socket CR-MO Steel 78mm Length Metric Sizes

* Made of chrome-moly steel construction for strength and durability. * To prevent rust and corrosion the black phosphate finish absorbs and retains oil repelling moisture. * 12-point opening is suitable for double hex (12-sided) hex and square fasteners can grab fasteners quickly at multiple angles. * To prevent round-off under stress it grips the flat sides of fastener heads instead of the corners. * The through-hole at the drive end locks on the tang of drivers or impact wrenches so it won t fall off or stick on the fastener head. * Widely used in DIY hand-making household maintenance and most general repairs.
