This professional-grade 20-piece set features S2 steel bits press-fitted into sockets for a permanent, non-loosening connection. Precision-machined hexagonal tips and chamfered ends ensure an exact fit and easy engagement with fasteners, while polished chrome plating provides superior corrosion resistance.

• S2 steel bits are press-fitted into sockets to create a straight, permanent connection that prevents loosening over time.
• Precision-machined 6-sided hexagonal tips ensure an exact fit with fasteners, while chamfered ends allow for easy sliding.
• Large, die-stamped size markings are permanently impressed into the steel for easy reading in low-light conditions.
• Four detent grooves provide a secure connection to drive tools, complemented by a through-hole for use with retaining pins.
• Polished chrome plating offers high corrosion resistance and a mirror finish that wipes clean easily.
• Specialized clear coat protection in deep socket wells prevents rust where traditional plating is thin.
• Includes a twist-to-lock socket rail to organize and secure your tools in the toolbox or on the go.
• Comprehensive 20-piece set includes 10 SAE (5/64 in. to 5/16 in.) and 10 metric (2 mm to 8 mm) hex bit sockets.
