The Wacker Neuson Washer 1/2 Flat is a genuine OEM component designed for HPG, HE, SE, and SP series vibratory truss screed power and end sections. As a direct OEM replacement, it is manufactured to the original dimensional and material standards, ensuring correct load distribution and fastener retention across all compatible assemblies. This washer fits a wide range of Wacker Neuson vibratory truss screed configurations, including the HPG100A, HPG50A, HPG100, HPG50, HE100, HE50, HE25, SE75, SE50, SE25, SP75, and SP50. Keeping hardware like the to OEM specification helps maintain torque integrity and protects mating surfaces throughout the service life of the screed.
Key Features
- Genuine OEM Material Consistency — Manufactured to the original hardness and dimensional spec, so load is distributed evenly across fastener interfaces without deformation under vibration.
- Direct Hardware Match — The 1/2-inch flat profile seats flush against mating surfaces as originally engineered, requiring no rework or shimming during installation.
- Broad Screed Family Coverage — Fits HPG, HE, SE, and SP series vibratory truss screed power sections and end sections, making it a practical stock item for mixed Wacker Neuson screed fleets.
- Vibration-Resistant Fastener Integrity — In high-cycle vibratory screed applications, an undersized or worn washer allows fastener loosening; the correct OEM washer maintains clamping force under continuous operation.
- Verified Part Number — Sourced directly under Wacker Neuson part number 5000116456, eliminating guesswork when cross-referencing the original parts manual.
A flat washer distributes the clamping load of a bolt or nut over a wider surface area, preventing the fastener from pulling through or deforming the material it secures. In vibratory screed assemblies, where continuous oscillation creates repetitive stress on every fastened joint, using the correctly sized washer is critical to maintaining torque and preventing loosening over time. A missing or incorrect washer can accelerate wear on mating surfaces and lead to fastener failure that disrupts screed operation.
