Ingco 12mm Deep Hexagonal Socket | 1/2-Inch Square Drive 6-Point Metric Chrome Vanadium Spanner Head (HHAST12123L)

The Ingco HHAST12123L Deep Hexagonal Socket is a professional-grade mechanical fastening accessory engineered to deliver high torque to 12mm hex-head bolts and nuts. Featuring an extended deep-profile body measuring 78mm in length, this socket is specifically designed to bypass long protruding threaded studs and safely reach deeply recessed fasteners located within tight structural enclosures.

The tool is manufactured from premium 50BV30 Chrome Vanadium (Cr-V) steel and undergoes a specialized heat-treatment process to maximize structural elasticity and resistance against stripping or cracking under heavy loads. It features a precision-machined 6-point (6pt) internal configuration that optimizes surface contact along the flat sides of the fastener rather than the corners, preventing rounding over time. The exterior surface is finished with a premium black nickel plating, providing advanced barrier protection against surface rust, oxidation, and industrial abrasive wear.
