Wacker Neuson 5000010373 Washer B6.4 Flat

The Wacker Neuson Washer B6.4 Flat is a genuine OEM hardware component used across an exceptionally wide range of Wacker Neuson equipment, including RD tandem rollers, RT and RTL trench rollers, CT and CRT concrete trowels, GP and GPS portable generators, LTN and LTW light towers, VP and DPU vibratory plates, and several other machine families. As a direct OEM replacement sourced through authorized Wacker Neuson supply channels, part number matches the exact material grade, thickness, and bore specification of the original hardware installed at the factory. Whether you are servicing an RD12A-90 tandem roller, an RT82-SC2 trench roller, a CT48 walk-behind trowel, or a GP5600A generator, this flat washer reinstalls without any modification to fastener assemblies or mounting hardware. Keeping correct-specification washers in stock is a straightforward way to ensure structural fastener assemblies maintain proper clamping loads during routine maintenance and field repairs.

Key Features

• Genuine OEM Material Grade — Manufactured to Wacker Neuson's specified bore diameter and thickness tolerances for the B6.4 flat washer designation, ensuring consistent clamping surface area and load distribution across fastener joints.
• Direct Hardware Match — Sized to seat flush against B6.4-compatible fastener assemblies; drops straight into existing bolt and screw positions without filing, shimming, or rework.
• Exceptionally Broad Fitment — Confirmed fit across RD tandem rollers, RT and RTL remote-controlled trench rollers, CT and CRT concrete trowels, GP and GPS portable generators, LTN and LTW light towers, VP single-direction vibratory plates, DPU and BPU reversible vibratory plates, BFS floor saws, EH electric breakers, and additional machine families.
• Correct Clamping Load — A properly sized flat washer distributes bolt load evenly across the mating surface, preventing fastener pull-through, housing deformation, and loosening under vibration — critical on compaction and demolition equipment.
• Stocking Convenience — One part number covers dozens of machine models, making 5000010373 a practical addition to a field service or shop inventory for mixed Wacker Neuson fleets.

A flat washer serves as a load-spreading interface between a fastener head or nut and the surface it clamps against. By increasing the bearing area of the fastener, it prevents the bolt or screw from pulling through or damaging softer housing materials, and it helps maintain consistent clamping force across the joint. On equipment that operates under continuous vibration — such as vibratory rollers, trench rollers, and plate compactors — washers also act as a buffer that resists fastener loosening over time. When a washer is missing, undersized, or deformed, the fastener loses clamping integrity, which can lead to progressive loosening, component shift, or structural damage to the assembly it secures.
