【Size】1" square drive, 75mm 12-point socket, 100mm (3.94") total length. 【CR-MO Steel】Forged with chrome-molybdenum steel provides excellent durability and strength with every impact movement; black phosphate finish for extra protection against rust and corrosion. 【Design】Radiused corners prevent fastener wear and increase the torque on fasteners by placing force on fastener's flat sides, rather than fastener corners. 【Pin Hole】Individual pinhole base design adds extra security by placing in a locking pin for stability when exerting strong torque motion,. 【Widely Use】For disassembly and tightening of double hex (12-sided), hex and square head bolts and nuts, especially suitable for requiring large torque and narrow space. The product has no insulation properties and is not suitable for electrical environments. * 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.
