The Wacker Neuson Lock Washer B8 is a genuine OEM fastening component designed for use across multiple Wacker Neuson machine families, including the RD25 tandem roller, BTS 13 and BTS 11 cut-off saws, and the DPU 2440H reversible vibratory plate compactor. As a genuine OEM part, the is manufactured to the exact material grade and dimensional tolerances specified for these machines, ensuring proper clamp load and thread retention in the fastener assemblies where it is installed. This lock washer is a direct-fit replacement sourced from Wacker Neuson's authorized parts supply chain, so it installs without modification against existing hardware. Confirm your machine's model number before ordering to ensure the is the correct washer specification for your application.
Key Features
- Genuine OEM Material Grade — Manufactured to the exact hardness and surface finish specification required for consistent clamp-load retention in Wacker Neuson fastener assemblies.
- Direct Hardware Match — B8 sizing aligns precisely with the corresponding bolt or stud diameter used in these assemblies, seating flush without rework to existing hardware.
- Broad Cross-Family Fitment — Confirmed fitment across the RD25 tandem roller, BTS 13 and BTS 11 cut-off saws, and the DPU 2440H reversible vibratory plate compactor.
- Prevents Fastener Back-Out — The locking geometry bites into mating surfaces under torque, resisting vibration-induced loosening — critical on high-vibration compaction and cutting equipment.
- Fastener Safety on High-Vibration Equipment — On machines that generate continuous vibration in operation, a worn or absent lock washer can allow critical fasteners to work loose, creating a safety and structural concern that a correct replacement directly addresses.
A lock washer is a thin hardened ring installed beneath a nut or bolt head to resist vibration-induced loosening in a fastened joint. As the fastener is tightened, the washer's spring tension or bite geometry creates friction that keeps the assembly from backing out during machine operation. On high-vibration equipment such as vibratory plate compactors, tandem rollers, and cut-off saws, this function is especially important — a loose fastener in a structural or mechanical assembly can accelerate wear on surrounding components or compromise the integrity of the joint entirely. Replacing a damaged or missing lock washer with the correct OEM part restores the clamping integrity the original assembly was designed to maintain.
