Roller Bolt Hardware Kit
SAF-Holland

A dedicated hardware kit for roller bolts supports the smooth articulation and secure operation of the fifth wheel locking interface. Roller bolts play a key role in maintaining accurate alignment of the jaws and providing controlled engagement and release under heavy loads. Worn or missing fasteners, spacers, or related hardware can produce excessive play, uneven wear, or binding during coupling. This kit supplies replacement rollers, bolts, nuts, and related hardware designed to match OEM geometries and tolerances, enabling reliable operation, ease of maintenance, and reduced downtime. VMRS 059-001-032 situates the item within the standardized series for fifth wheel components and hardware, with category 42521 indicating the fifth wheel sub-assembly group. Compatible with a broad spectrum of fifth wheel products and aftermarket equivalents, installers should confirm model-specific clearances and apply appropriate lubrication per schedule. In service, consistent roller-bolt performance contributes to smoother cycles, safer low-speed releases, and extended service life of the locking assembly.
