Specifications

The AFF 18520 Locknut Socket offers professional-grade durability in a compact 2¼″, 6‑point configuration tailored for wheel-bearing locknuts. The machine-welded ¾″ drive plate ensures a secure and robust connection to ratchets, breaker bars, or torque wrenches. Crafted from high-tensile steel with a corrosion-resistant powder-coat finish, it withstands frequent use in tough conditions. Chamfered edges facilitate quick alignment, while double laser-etched part and size markings stay visible even in greasy environments. Each socket is individually boxed, labeled with a barcode, and ready for efficient inventory management. Whether you're servicing trucks, trailers, or farm machinery, the 18520 delivers precise fit, rugged strength, and long-term reliability.
