PBTEK Half Inch Drive M12 Spline Bit Socket 8 Inch Long S2 Alloy Steel Bit CRV Socket Precision Chamfered End Size Marked for Hand Use Piece

This 1/2-inch drive M12 (12mm) triple square spline bit socket measures 8 inches in total length, making it ideal for accessing deep or hard-to-reach fasteners in automotive and mechanical applications

The bit is crafted from quenched and heat-treated S2 alloy steel with a hardness rating of 58-60 HRC, providing exceptional durability and resistance to wear for long-lasting performance under demanding conditions

The socket is constructed from high-strength chrome vanadium steel, which enhances turning power and ensures reliable torque transmission when used with a compatible ratchet or hand tool

Bit tips are automatically processed for precise sizing, and chamfered ends allow smooth insertion into fastener heads, reducing the risk of stripping and minimizing wear during repeated use

Clearly stamped size markings on the socket body allow for quick identification and faster tool selection, streamlining workflow and reducing downtime in busy work environments

Designed for hand use only, this spline bit socket is perfect for tightening or loosening spline drive fasteners in vehicles, machinery, and equipment; not intended for use in electrical environments
