Specifications

The American Forge & Foundry 18521 Locknut Socket offers a precision-engineered 2½″, 6‑point hex configuration ideal for wheel-bearing locknuts. Constructed from high-tensile steel with a machine-welded ¾″ drive plate, it ensures maximum torque transfer without slipping. Its chamfered entry contributes to easy socket alignment and secure engagement, while the black powder-coat finish provides excellent corrosion resistance. Laser-etched size and part number markings remain visible under grease or heavy use. Each socket comes in its own barcoded box for organized storage and quick inventory tracking. Built to excel in demanding shop floors and field service environments, the AFF 18521 offers durability, precision, and veteran-level performance for heavy-duty truck and trailer maintenance.
