Reach recessed fasteners and master high-torque mechanical operations with the professional performance of the INGCO HHAST12163L Deep Hexagonal Socket. Forged to standard industrial specifications, this 16mm single socket piece features a specialized deep-wall profile, making it indispensable for loosening or tightening nuts situated over protruding, long threaded bolts—such as spark plugs or deep automotive chassis studs—or nestled deep within cramped machinery channels. Designed to withstand rigorous use in automotive garages and structural steel workshops, it attaches seamlessly to any standard 1/2-inch square drive ratchet, breaker bar, or impact adapter.

Manufactured from premium-grade 50BV30 Chrome Vanadium (Cr-V) steel, the socket undergoes advanced thermal heat treatment to achieve maximum structural core strength and high elasticity under sudden peak loads. Its interior layout is precision-engineered as a 6-point (hexagonal) configuration, allowing the walls to grip flat fastener sides securely rather than just hitting the corners. This critical design feature ensures even torque distribution and significantly reduces the risk of rounding off expensive or stubborn fasteners. Finished with a sleek, high-protection black nickel plating, it naturally repels rust, grease, and industrial corrosion, maintaining pristine operational performance over a lifetime of hard work.
