Hex Nut
SAF-Holland

Heavy-duty hex fastener designed to secure components within the brake and related hardware ecosystem, this nut provides clamping strength critical to maintaining alignment and preventing loosening under dynamic loads. It is a standard hardware item used across traction systems, linkages, and mounting points where robust locking is required to resist vibrations and torque fluctuations. The VMRS code 053-007-004 places it in the hardware family, while the category 42590 clarifies its use as a component fastener in heavy-duty applications. The nut pairs with compatible bolts and plates to form secure joints, and its dimensions are sized to support common industry thread sizes and load ratings. For maintenance or replacement, technicians should inspect thread engagement and seating for signs of wear, distortion, or corrosion, and follow prescribed torque values to ensure reliable retention. In fleet service, using high-quality hex nuts helps maintain structural integrity of the brake assemblies, protects against inadvertent loosening, and contributes to safer operation in challenging road conditions and heavy payloads.
