Wacker Neuson 5000158458 Flange Bolt

The Wacker Neuson Flange Bolt is a genuine OEM Flange Bolt used across a broad range of Wacker Neuson equipment, including CT and CRT concrete trowels, GP and GV portable generators, PT and PDT trash pumps, VP and WP vibratory plates, BPU reversible vibratory plates, and BFS floor saws. As a direct OEM replacement, this bolt is manufactured to the same specifications as the original hardware installed at the factory, ensuring correct thread engagement, clamping load, and head geometry for each application it serves. Fitment has been verified across dozens of individual model configurations spanning multiple equipment families. Stocking this part means you are prepared for routine maintenance and unplanned repairs across a wide variety of Wacker Neuson machines.

Key Features

• OEM-Spec Thread and Head Geometry — Manufactured to the exact thread pitch, shank diameter, and flange bearing surface dimensions specified for each machine, ensuring correct torque transfer and clamp load without galling or backing out.
• Integrated Flange Bearing Surface — The built-in flange distributes clamping load evenly across the mating surface, eliminating the need for a separate flat washer and maintaining consistent joint integrity during operation.
• Broad Cross-Family Fitment — Verified for use on CT and CRT walk-behind and ride-on concrete trowels, GP and GV portable generators, PT and PDT trash pumps, VP, WP, and BPU vibratory plates, BFS floor saws, and additional Wacker Neuson equipment families.
• Genuine OEM Part — Sourced directly through Wacker Neuson, this is the same bolt supplied in original production, so thread class, material grade, and surface treatment all match what the machine was designed to accept.
• Critical Fastener for Structural and Drive Assemblies — Flange bolts in this equipment family secure covers, housings, engine mounts, and drive components; a damaged or incorrect bolt can lead to loosening under vibration and potential assembly failure.

A flange bolt combines a standard hex bolt with an integrated wide-diameter flange just below the head, which acts like a built-in washer to spread clamping force over a larger surface area. This design is commonly used in high-vibration assemblies — such as engine mounts, guard covers, and drive housings — where a conventional bolt-and-washer combination might loosen over time or allow fastener pull-through in softer materials. When a flange bolt is worn, cross-threaded, or replaced with an incorrect substitute, the joint can lose preload under operational vibration, leading to loosening, misalignment, or accelerated wear of the surrounding components. Using the correct OEM specification bolt maintains the designed clamping load and keeps critical assemblies secure through the full service life of the machine.
