Forged with chromium molybdenum steel material, surface heat treatment, high strength and durability. To prevent rust and corrosion, the black phosphate finish absorbs and retains oil, repelling moisture. 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. It has a radius corner design, causing the socket to grasp the sturdy wall of the fastener instead of the corners, thereby reducing the wear of the fastener. Widely used in DIY hand-making, household maintenance, and most general repairs.
