Key Features
- Genuine OEM Hardware Spec — Manufactured to the exact dimensional standard (DIN 125A) as the original washer, ensuring correct load distribution across mating surfaces.
- Drop-In Replacement — Sized specifically for 4MM fastener assemblies, this washer installs directly into any position requiring the original 58042 hardware with no rework needed.
- Broad Equipment Compatibility — Fits MRH800GS and MRH601DS walk-behind rollers, GAW180HE series gasoline arc welders, and GA3.6HR, GA6HR, GA6HEB, and GA6HB generator models.
- Proper Load Bearing — A correctly rated flat washer distributes clamping force evenly across fastened joints, preventing surface damage, bolt pull-through, and loosening under vibration.
- Essential Service Stock — Small hardware like this washer is consumed during routine maintenance and rebuilds; having the correct OEM part on hand keeps service jobs moving forward without sourcing delays.
A flat washer is a thin, disc-shaped fastener component placed between a bolt head or nut and the surface being fastened. Its primary role is to spread the clamping load over a wider area, protecting the mating surface from damage and helping the assembly maintain its holding force under vibration and dynamic loads. When the wrong washer is used — or when one is missing — fastener joints can loosen prematurely, leading to misaligned components, accelerated wear on adjoining parts, and potential fastener failure in critical assemblies.
