The Wacker Neuson Washer Bolt 4X10 is a genuine OEM fastener designed for the P31A Power Unit for Wet Screed. Sourced directly from Wacker Neuson, this bolt delivers the exact thread engagement, shank diameter, and integrated washer bearing surface specified for the application — no guesswork on substitution. It confirms compatibility with the P31A series, so you can order with confidence and get the machine back in service without delays.
Key Features
- OEM-Matched Fastener Specification — Manufactured to the exact 4X10 dimensional standard, ensuring correct clamp load and thread engagement for the P31A assembly.
- Integrated Washer Head — The washer flange distributes bearing load evenly across the mating surface, protecting the surrounding material from pull-through or distortion during torquing.
- Direct-Fit for P31A Power Unit — Verified fitment for the Wacker Neuson P31A Power Unit for Wet Screed, matching the original hole pattern and hardware spec without modification.
- Genuine Wacker Neuson OEM Part — Produced to the same material grade and finish standard as the fastener installed at the factory, maintaining consistent performance across the assembly.
- Supports Structural Integrity of the Screed Drive System — A correctly specified bolt keeps critical components properly secured under vibration; a worn or incorrect fastener can lead to loosening, misalignment, and accelerated wear of adjoining parts.
A washer bolt is a fastener that combines a bolt shank with a permanently attached or integrated washer flange at the head. In a wet screed power unit, fasteners of this type are used to secure components that are subject to continuous vibration during operation. The washer face spreads clamping force over a wider area than a standard bolt head, preventing the fastener from working loose or damaging softer mating surfaces. When this bolt stretches, corrodes, or is replaced with an incorrect size, clamp load is compromised, which can allow assembled components to shift and wear prematurely.
