The Wacker Neuson Flange Nut 1/4-20 is a genuine OEM fastener designed for the G25 and G12 skid-mounted mobile generator series. As a direct OEM replacement, is manufactured to the same thread specification and flange geometry as the original hardware, ensuring a flush, secure seating surface without the need for additional washers. This flange nut is confirmed compatible with both the G25 and G12 mobile generator models in skid-mounted configuration.
Key Features
- Correct Thread Engagement: — Machined to the 1/4-20 UNC thread specification, delivering full thread engagement and the correct clamp load for the fastened joint.
- Integrated Flange Design: — The built-in flange distributes bearing load across a wider surface area, eliminating the need for a separate flat washer and maintaining consistent torque retention.
- Genuine OEM Part: — Sourced directly from Wacker Neuson, this fastener meets the same material and dimensional standards as the hardware originally installed on the generator at the factory.
- Confirmed Fitment for G25 and G12 Generators: — Verified for use on G25 and G12 skid-mounted mobile generators, so you can order with confidence that part number 5000117058 is the correct replacement.
- Maintains Structural Integrity: — A worn, stripped, or incorrect fastener can allow components to loosen under vibration; replacing with the correct OEM hardware keeps panels, guards, and assemblies securely fastened during operation.
A flange nut is a hex nut with a wide, integrated washer-like base on one face. That flange spreads the clamping force over a larger contact area, which helps prevent loosening caused by engine vibration — a common challenge in generator applications. When a flange nut becomes stripped, corroded, or lost during service, replacing it with a fastener of the correct thread size and flange diameter is essential to restore the joint's original holding strength. Using an undersized or incorrect substitute risks allowing fastened panels or components to work loose during operation.
