Bolt - 3/4-10 x 4.25, Grade 5
SAF-Holland

A rugged Grade 5 bolt with a 3/4-10 thread and a 4.25 inch grip length provides enhanced strength for demanding suspension and structural connections. This fastener is designed to handle higher shear loads and greater fatigue resistance than standard hardware, supporting critical joints in trailer axles and suspension assemblies. VMRS 053-007-005 anchors it in the suspension hardware family, aiding maintenance planners in selecting the correct specification for Long-Term reliability. Category context 42590 places emphasis on heavy-duty truck and trailer applications where robust fasteners contribute to sustained alignment, reduced downtime, and longer service intervals. Typical installation scenarios include securing mounting brackets to frame rails, attaching leaf spring hardware, and linking crossmembers. As with all high-strength fasteners, proper torque, thread lubrication, and periodic inspection are recommended to prevent loosening and ensure continued performance under vibration and temperature swings encountered in highway operation.
