SAF-Holland

A precision shoulder-mounted mounting bolt featuring a 12-point head and metric M18 x 1.5 thread with a 55 mm overall length. This fastener is intended for clamp or caliper mounting interfaces where accurate positional control and resistance to angular shift are essential. VMRS 013-001-129 places it within the mechanical fastener category used for braking and suspension assemblies, while category 42528 signals its role in caliper mounting hardware. The 12-point design aids tool engagement in tight spaces, improving assembly reliability in field repairs and workshop settings. Key benefits include robust load transfer, improved caliper alignment stability under vibration, and compatibility with standard torque procedures. When selecting this bolt, verify thread engagement, shoulder seating, and adjacent component clearances to ensure correct clamping force and long service life in heavy-duty trailer and tractor applications.
