Key Features
- Genuine OEM Material Grade — Manufactured to the original dimensional and material specification for correct load distribution and surface protection in these applications.
- Drop-In Fitment — Engineered to the correct 3/4 bore and outer diameter to seat properly without shimming or modification across all compatible models.
- Broad Model Coverage — Fits Essick EM-series and PRO-series mixers, Whiteman WM63 and WM70/90 series mixers, and the AR14H roller in a single part number.
- Prevents Fastener and Surface Damage — Properly sized washers distribute clamp load evenly, protecting mating surfaces and preventing bolt heads or nuts from pulling through or deforming the assembly.
- Supports Scheduled Maintenance and Repairs — Having the correct OEM washer on hand keeps hardware assemblies torqued to spec, preserving the integrity of critical fastened joints over the machine's service life.
A flat washer serves as a load-spreading interface between a fastener — such as a bolt head or nut — and the surface it bears against. By distributing clamping force over a wider area, the washer protects softer or thinner mating surfaces from damage and ensures the fastener maintains its holding strength under vibration and operational stress. When the wrong washer is used, or when a washer is missing entirely, fasteners can work loose prematurely, surfaces can deform, and structural integrity of the assembly can be compromised — making correct washer selection an important detail in any repair or reassembly job.
