Oversized Hex Lock Boss
SAF-Holland

Oversized hex lock boss designed for high-torque fastener applications in safety-critical wheel-end and suspension assemblies. The component provides a rugged, precisely machined interface capable of transmitting clamp loads reliably under vibration and shock, while maintaining reduced risk of galling or thread damage. Hardened materials and tight tolerances ensure long-term lock integrity, even in demanding on-road conditions. The design prioritizes ease of installation with standard hand tools and consistency of torque transfer across fastener runs. Category 42745 situates this item among specialized fastener accessories for robust wheel-end and suspension components. VMRS classification 077-003-044 identifies it as part of the oversized lock-boss family, enabling interoperability with corresponding fasteners and hubs within SAF-Holland products. Cross references are not listed, but the part is widely used in high-torque hub connections and other heavy-duty assemblies where a durable, tight-fit interface is essential for reliability in harsh operating environments.
