SATA SC34210 3/8" Drive 6 Point Impact Socket 15mm

A 6-point socket grips hex fasteners on six flat faces, providing better contact and reducing rounding under heavy torque. This makes it more durable in high-torque, impact applications than many 12-point designs.

Off-corner loading shifts contact away from the sharp corner of the fastener, reducing rounding and wear during heavy impacts. It helps extend tool life and improves gripping reliability in demanding tasks.

The socket is crafted from chrome molybdenum steel (Cr-Mo) for high strength and durability, and it features a black phosphate coating for corrosion resistance and extended life in challenging environments.

This socket uses a 3/8" drive and fits 15mm fasteners. The combination provides a balance of power and accessibility for mid-sized fasteners.

Yes. It is specifically engineered for use with impact wrenches, offering the strength and durability needed for heavy-duty and high-torque applications.

Common uses include automotive repair, machinery maintenance, and general mechanical work where 15mm fasteners are prevalent and high-torque fastening/loosing is required.

Keep it clean and dry, inspect for any signs of damage or rust, and store it in a protective case or tray. The Cr-Mo steel and black phosphate coating benefit from basic care to minimize corrosion and wear.

The 15mm version sits between the 14mm (for smaller fasteners) and 17mm (for larger fasteners) in the same 3/8" drive, 6-point, impact-rated family. All share Cr-Mo construction and the off-corner loading feature; you’d choose based on your fastener size need.

Wear eye protection and gloves as appropriate, ensure the fastener is correctly seated before applying torque, inspect the socket for cracks or damage before use, and avoid using damaged sockets or exceeding manufacturer torque recommendations.

It uses high-strength chrome molybdenum steel, a protective black phosphate coating for corrosion resistance, and an off-corner loading design to reduce fastener rounding. Together, these features provide greater durability and reliability for professional or demanding DIY use.
