• 【Size】 1/2-inch drive, 21mm 6-point socket, 39mm (1.53-inch) total length.
• 【CR-MO Steel】 Provides the strength and flexibility to handle high torque impact tools.
• 【Radius Corner Design】Reduces wear and increases torque on fasteners by placing force on fastener walls rather than fastener corners.
• 【Shallow Body】Allows socket to fit into tight, narrow spaces; precision surfaces move smoothly against various surfaces.
• 【Size Markings】Large markings for quick socket identification.

* Made of high-grade Chrome-Moly steel for strengthen and durable to use. * To protect against rust and corrosion, the black phosphate finish absorbs and holds 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.
