Bolt - Hex Head
SAF-Holland

In heavy-duty trailer and axle applications, an extended-length hex head fastener supports through-bolt and mounting configurations where standard bolts would short-change engagement or clearance. The size range of the hex head (1.63 to 1.68 inches) and overall length of 9.53 inches provide pronounced engagement with thick brackets and cross-members, while a head height of approximately 0.65 to 0.71 inches maintains sufficient clearance for tools and wrench access during installation and service. The thread size of 1 1/8 inches and a thread length of 1.35 inches offer robust thread engagement in through-holes, contributing to consistent preload and resistance to loosening under vibration. As part of the Trailer Axle and Suspension family, this fastener aligns with VMRS code 053-007-005, ensuring compatibility with maintenance data, diagnostics, and repair procedures. Category 42590 reinforces its role in heavy-duty suspension hardware. While no additional cross-references are listed, technicians typically pair this type of through-bolt with matching nuts, washers, and mounting brackets to secure cross-members, mounting ears, and anchor points, delivering dependable load paths and reducing the potential for misalignment during routine servicing or fleet operations.
