U-Bolt 1 8x10 5 Grade 8
SAF-Holland

This high-strength fastener assembly secures leaf-spring configurations in trailer axles and suspension systems, providing a stable clamp that maintains spring alignment under load, braking, and rough road conditions. The unit is specified with an 1/8 inch diameter and a 10 inch length, designed to withstand dynamic forces without loosening when torqued to standard hardware specifications. Constructed for Grade 8 performance, it delivers reliable clamp load and resistance to fatigue across long service intervals in heavy-duty trailer applications. The geometry creates uniform load distribution across the leaf pack, reducing spring shift and axle misalignment that can lead to handling issues or uneven tire wear. Typical installations pair this fastener with corresponding bearing saddles and lock nuts to maintain retention under harsh environments. As part of the Trailer Axle and Suspension category, its use complements compatible spring assemblies, mounting plates, and frame hardware to ensure safe, compliant operation on commercial trailers. VMRS code 016-008-005 is used to classify its function within vibration and suspension components, reinforcing its role in securing suspension subsystems during service life.
