• 【CLEARLY SIZE】-High-contrast size marking is permanently laser etched and easy to read, even in low light. 1/2-inch drive,21mm 6-point socket. 【1/2-INCH-DRIVE CHROME SOCKET SET】 - Sockets are the perfect companion for automotive work. By grabbing nuts and bolts on all six sides, there is far less chance of rounding fasteners by using sockets compared to open-end wrenches. The sturdy Cr-V material used in these sockets allow for relatively thin walls, allowing you to access nuts and bolts with tight clearances in hard-to-reach areas. 【MATERIAL】-Chrome vanadium steel construction for strength and durability. Mirror chrome plated finish to resist corrosion. 【6-POINT SOCKET DESIGN】-The 6 point sockets are designed for off-corner loading, putting the force on the flats of the fasteners rather than the corners. This reduces the chances of rounding fastener heads and delivers the maximum amount of torque to reliably tighten and loosen difficult nuts and bolts. 【APPLICATIONS】-Extra-deep broach reaches over long, threaded shafts to access nuts. Detent notches in drive end lock onto ratchets and extensions.. Widely used in DIY hand-making, household maintenance, and most general repairs.
