• Heavy-Duty Impact Build: Forged from high-strength alloy steel and treated with a protective black oxide coat, this socket bit absorbs the severe shock impacts of heavy power tools without fracturing or chipping.
• Fixed-Insert Design: The 9/16" hex bit is tightly pressed into the 3/4" square drive base. This eliminates wobble, ensures absolute radial alignment, and delivers optimal mechanical torque transfer down into the fastener body.
• Side Locking Hole: The drive end incorporates a precision-drilled side locking hole designed to accommodate a retention pin and ring or an anvil detent ball, keeping the socket safely locked to the tool during high-speed vertical and upside-down operations.
• Stamped Size Markings: Sizing text is deeply stamped directly into the metal shell, making quick identification a breeze even when covered in heavy grease or working in low-light environments.
