Plug Washer
SAF-Holland

Compact plug washer with an outer diameter of 0.50 inches is used to seat and seal fasteners within tight spaces in SAF-Holland assemblies. It functions as a spacer and anti-rotation element in conjunction with bolts and female threads, ensuring proper depth seating and consistent preload in critical joints. The VMRS 053-007-008 classifies it within the general washer family used for husbanding hardware in trailer and tractor applications. Category 42595 places it among the standard hardware components for structural joints and mounting brackets across SAF-Holland product lines. The plug washer is typically selected for assemblies where space constraints demand a small, defined seating surface and where precise torque control is required during servicing. There are no cross references listed; always measure the host hole and bolt diameter to confirm compatibility before installation. Routine inspection and replacement during maintenance helps maintain joint integrity and minimize loosening in dynamic operating conditions.
