First, our sockets are forged from industrial-grade Chromium Vanadium (Cr-V) steel, then machined to tight tolerances, heat treated, polished and finally coated with a durable chrome plating for a protective mirror finish. These are not your average tools; these sockets are engineered for a lifetime of heavy professional use. ★ 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. ★ 18PC COMPLETE METRIC SET – This 1/2-inch drive shallow chrome socket set includes every metric size from 10 mm to 27 mm with no sizes skipped! Sizes included: 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27 mm. Every unit is meticulously inspected for a consistent chrome-plated finish to ensure maximum corrosion resistance, meaning that these sockets are truly made to last a lifetime. » ★ 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.
