The Wacker Neuson is a genuine OEM Lock Washer 5 designed for the HSH350 hydronic surface heater, E1100 ground heater, and DPU 5045H reversible vibratory plate compactor series. As a direct OEM replacement, part is manufactured to the exact material grade and dimensional specification of the original hardware, ensuring a secure, rattle-free fastening connection right out of the box. It fits across multiple machine families — from heating equipment to heavy-duty reversible compaction plates — so verify your model number before ordering. Keep a spare on hand; a missing or deformed lock washer can allow fasteners to back out under vibration, leading to loose assemblies and potential component damage.
Key Features
- OEM-Grade Hardness and Temper — Manufactured to the original spring-steel specification, delivering the correct bite and retention force needed to resist loosening under sustained machine vibration.
- Drop-In Hardware Replacement — Matches the original size 5 profile exactly, seating flush against the mating surface without filing, shimming, or adjustment.
- Broad Model Compatibility — Confirmed fit across the HSH350 hydronic surface heater, E1100 ground heater, and DPU 5045H reversible vibratory plate compactor families.
- Vibration Resistance — The locking geometry bites into both the fastener and the mating surface, maintaining clamp load on assemblies that experience continuous operational vibration.
- Genuine Wacker Neuson OEM Part — Sourced directly from Wacker Neuson, carrying the correct part number 5000010709 for confident, catalog-verified ordering.
A lock washer sits between a bolt or nut and the surface it clamps, using a split or toothed profile to resist rotational loosening caused by vibration and dynamic loads. On equipment like vibratory plate compactors and surface heaters, fasteners are exposed to constant mechanical vibration and thermal cycling — conditions that cause standard washers to allow gradual fastener back-out. When a lock washer is worn flat, cracked, or missing entirely, the fastener loses clamping force, assemblies can shift or rattle loose, and in severe cases critical components may separate during operation. Replacing a damaged or missing lock washer with the correct OEM part restores the engineered clamping integrity of the joint.
