* 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.* 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 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.Specifications:* Socket Size: 8mm/10mm/12mm/13mm/14mm/15mm/16mm/17mm/18mm/19mm* Drive Size: 1/2-inch* Total Length: 78mm / 3-inch* Material: Chrome-Molybdenum Steel (CR-MO)* Finish: Black Phosphate* Color: BlackPackage Content:* 1 x 6-Point Impact Socket Set
