As a direct OEM replacement, this flat washer matches original material and dimensional specifications, ensuring correct load distribution and a secure assembly fit across the wide range of compatible models. Whether you are servicing a ground heater on an active winter jobsite or performing scheduled maintenance on a hydronic surface heater system, using the correct Wacker Neuson Flat Washer keeps the assembly performing as intended.
Key Features
- Genuine OEM Material Spec — Manufactured to Wacker Neuson's original material and hardness standards, ensuring correct load-bearing performance for heating system fastener assemblies.
- Drop-In Replacement — Matches original hole diameter, outer diameter, and thickness so it seats correctly against mating hardware without modification.
- Broad E-Series and HSH-Series Fitment — Compatible across E3000, E2200, E5000, E1250, E1100, HSH700G, HSH650, HSH380S, HSH380B, and HSH350 models, covering a wide range of hydronic surface heaters and ground heaters.
- Consistent Clamping Force — A correctly sized flat washer distributes fastener load evenly across the joint surface, preventing housing distortion and fastener pull-through in heating equipment enclosures.
- Verified OEM Part Number — Ordering by Wacker Neuson part number 5200005254 confirms you receive the exact washer specified for these machines, not a generic substitute.
A flat washer serves as a load-distributing interface between a fastener — bolt, screw, or nut — and the surface it clamps against. By spreading the clamping force over a wider area, it prevents the fastener head or nut from embedding into or distorting softer housing materials, and helps maintain consistent tension in the joint over time. In hydronic surface heating and ground heating equipment, where assemblies are subject to repeated thermal cycling, vibration, and outdoor environmental exposure, a worn, undersized, or incorrect washer can lead to loose fasteners, housing damage, or fluid system leaks at critical connection points.
