Drive By 6-Point Impact Socket, CR-MO, Standard 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.* 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.Specifications:* Socket Size: 30mm* Drive Size: 1-inch* Total Length: 80mm / 3.15-inch* Material: Chrome-Molybdenum Steel (CR-MO)* Finish: Black Phosphate* Color: BlackPackage Content:* 1 x 6-Point Impact Socket
