Wacker Neuson 5100015431 Washer Flat Class 8.8 M8

The Wacker Neuson Washer Flat Class 8.8 M8 is a genuine OEM component designed for the Angle Broom 84. Sourced directly from Wacker Neuson, this washer meets the original engineering specifications the machine was built around, ensuring a correct, consistent fit every time. It is confirmed compatible with the Angle Broom 84 series, making it a straightforward like-for-like replacement when servicing or reassembling your equipment.

Key Features

• Class 8.8 Hardness Rating — Meets the mechanical strength grade specified for this fastener position, providing the load-bearing capacity the joint was engineered to handle.
• Genuine OEM Part — Supplied by Wacker Neuson as part number 5100015431, identical to the washer installed at the factory — no guesswork on sizing or material grade.
• M8 Sizing for Direct Installation — Dimensioned to seat correctly on an M8 fastener, dropping straight into position without modification during reassembly.
• Confirmed Fitment for Angle Broom 84 — Verified against Wacker Neuson parts documentation for the Angle Broom 84, so you can order with confidence.
• Correct Clamping Load Distribution — A properly spec'd flat washer spreads fastener load evenly across the mating surface, protecting the joint from distortion and loosening under vibration.

A flat washer acts as a load-distribution interface between a fastener head or nut and the surface it bears against. By spreading clamping force across a wider area, it prevents the fastener from pulling through or damaging softer materials and helps maintain consistent joint tension over time. On equipment subject to continuous vibration — like a power broom — using a washer of the correct grade and diameter is essential to keeping assemblies secure throughout the machine's working life. A worn, undersized, or incorrect washer can lead to fastener loosening, surface damage, and premature joint failure.
