Jet Tools standard length SAE and Metric sockets are forged from premium chrome vanadium steel and designed to provide maximum durability, torque, and access. All items meet U.S. Federal Specifications: GGG-W-641e, Canadian Government Specification CDA39-GP-12b and ANSI specifications. WARNING: Do not use chrome sockets on electric or air impact wrenches. Chamfered edges allow easiest socket placement on fastener, increasing productivity and reducing frustration. Full polish chrome finish cleans easily and resists corrosion. Laser etching and hard stamp ensures permanent socket identification
