STEELMAN 11-Piece Swivel Head 3/8-in Drive, 9-in Metric Impact Extension Socket Set

The 97886 STEELMAN PRO 11-Piece Swivel Head 3/8-Inch Drive, 9-Inch Metric Impact Extension Socket Set was designed to get into hard-to-reach spaces where maximum power is needed. This set includes 11 swivel-tip extensions made of high strength, heat treated 4140 chromoly steel with a black oxide finish. The knurled shaft allows for easy hand-starting and tightening of fasteners to prevent cross-threading. The pinless joint design transfers more usable torque to fasteners than a universal joint design, and also provides safety from flying projectiles that such designs can create upon failure. Each socket can pivot up to 30 degrees, providing a high degree of flexibility and allowing for a wide range of applications. The metric sizes included in the set are: 9, 10, 11, 12, 13, 14, 15, 16, 17, 18 and 19mm.
