93400502
Lock Nut - 1/8
SAF-Holland

In demanding trailer axle and suspension systems, this small yet critical fastening element delivers reliable performance at a compact thread size of 1/8 inch UNC. The flat end width of 25.40 millimeters supports stable seating on bearing surfaces and helps distribute clamp load evenly across contact areas, minimizing localized stress. Constructed from steel, the component delivers strength and fatigue resistance necessary for repeated assembly and disassembly during maintenance cycles. It is part of the trailer axle and suspension family, reflecting its role in securing critical connections within the trailer’s suspension geometry and wheel-end assemblies. VMRS code 053-007-035 places it squarely in the vehicle maintenance and repair domain, emphasizing its function in maintaining proper bolt preload and joint integrity. Cross references to HLD 93400500 and TDA R304421 aid parts planners by providing compatible alternatives. Use in applications requiring precise 1/8 inch screw engagement with dependable locking characteristics helps ensure consistent alignment, reduced wear, and extended service intervals in highway trailers operating under high vibration and load conditions.
