20 Pc. X10 3/8' Drive 6 Point Standard SAE/Metric Mecanics Tool Set

Superior strength from the specially formulated and heat-treated Crestoloy® alloy steel construction. Black manganese phosphate finish for extreme corrosion resistance and smooth ground surfaces to reduce friction. 84 tooth ratchet requires only 4.3° of movement, providing more efficiency and access in tight situations. Enclosed ratchet head design for improved reliability in the harshest environments. Teardrop low-profile head and flush-mounted lever is up to 21% slimmer than the competition. 6-point sockets with off-corner loading technology reduces fastener rounding. High contrast colored rings on sockets allow you to quickly identify between SAE and Metric sizes. Knurling on the ratchet and sockets give you better grip and control in slippery circumstances.
