The GEARWRENCH 7-pc 3/8" Drive Long Length Hex Bit SAE Socket Set, No. 82537, offers extended length hex bits for additional access to hard-to-reach fasteners. The S2 steel insert bits offer maximum strength, and the heat-treated socket bases provide lasting durability, the company says. Double line (SAE) and knurled (metric) rings help technicians easily identify standard and metric sockets, along with hard stamped size markings. The polished chrome finish wipes clean and resists corrosion. The set includes a socket rail for storage and organization. This set meets ASME specifications.
