SK Hand ToolsSK Tools 4090 40 Piece 3/8" Drive Standard & Deep, SAE & Metric Impact Socket Set.
The patented SureGrip hex design drives the side of the fastener, not the corner. This not only provides increased strength, but also avoids the rounding of rusted or damaged fasteners, which can occur when using a sharp hex tool.
Improved black coating retains more rust preventative compound than black oxide.
Extra recess depth to allow for use where threaded fasteners protrude above the nut or where the fastener is domed.
Made in the USA, featuring quality workmanship and value.
