The Wacker Neuson Flange Bolt (5X55) is a genuine OEM fastener designed for the P31A Power Unit for Wet Screed. Sourced directly from Wacker Neuson, this bolt is manufactured to the exact material and dimensional specifications required for proper assembly and clamping force in the application. If you are servicing or rebuilding a P31A wet screed power unit, using the correct OEM hardware ensures the joint integrity and torque retention the machine was engineered around.
Key Features
- OEM-Grade Fastener Material — Manufactured to the precise tensile strength and thread specification required for secure, lasting clamping in the P31A power unit assembly.
- Exact Dimensional Match — The 5X55 flange bolt installs directly into the original bolt pattern without modification, maintaining correct clamping load across mating surfaces.
- Genuine Wacker Neuson OEM Part — Supplied as an authorized Wacker Neuson replacement, so you can be confident the part meets the original design intent.
- Integrated Flange Design — The built-in flange distributes clamping load evenly, protecting mating surfaces and reducing the risk of fastener pull-through or joint loosening under vibration.
- Correct Fit for P31A Wet Screed Power Unit — Verified fitment for the P31A Power Unit for Wet Screed, making it the straightforward choice when replacing worn, stripped, or missing hardware during routine service.
A flange bolt combines a standard hex bolt with an integrated washer-like flange beneath the head, which spreads the clamping force over a wider surface area than a conventional bolt alone. In a power unit subjected to continuous vibration — as is typical in wet screed applications — this load distribution helps the fastener maintain its clamp load and resist loosening over time. A worn, stripped, or incorrect bolt in this position can compromise joint integrity, leading to misalignment, leaks, or structural failure at the connection point.
