The Wacker Neuson Wing Nut 3/8-16 is a genuine OEM fastener designed for the GPS and GS series portable generators. Sourced directly from Wacker Neuson, this wing nut delivers the exact thread specification and dimensional profile required for a secure, tool-free connection on your generator. It is compatible with a wide range of Wacker Neuson portable generator models, including the GPS9700, GPS8500, GS4.6A, GS4.6AE, GS4.6AI, GS5.6A, GS5.7A, GS5.7AE, GS5.7AI, and GS12Ai series. When a fastener wears, strips, or goes missing, replacing it with the correct OEM part keeps every assembly seated and torqued as the manufacturer intended.
Key Features
- Correct 3/8-16 Thread Specification — Matches the exact thread pitch and diameter called out in Wacker Neuson service documentation, ensuring full thread engagement without cross-threading or play.
- Genuine OEM Part — Manufactured to Wacker Neuson's original material and dimensional tolerances, so the wing nut seats flush and holds consistent clamping force under generator vibration.
- Broad GPS and GS Series Coverage — Fits GPS9700, GPS8500, GS4.6, GS5.7, GS5.6, GS9.7V, and GS12Ai portable generator models across multiple production variants and configurations.
- Tool-Free Tightening by Design — The wing profile allows hand-tightening and quick removal in the field, speeding up panel access, cover removal, and routine service tasks without additional tooling.
- Corrosion and Vibration Resistance — Built to withstand the continuous vibration environment of a running generator, maintaining clamp load and resisting loosening over extended run times.
A wing nut is a hand-tightened fastener used in locations where components need to be secured quickly and removed frequently — such as access panels, covers, and ancillary brackets on portable generators. The 3/8-16 designation refers to the thread diameter and thread count per inch, both of which must match the mating stud or bolt exactly to achieve full thread engagement. When a wing nut becomes stripped, cracked, or lost, the connected panel or component can vibrate loose during operation, creating both a service hazard and the potential for damage to surrounding parts. Replacing the 5000025679 with a genuine Wacker Neuson wing nut restores the correct clamping function and keeps the assembly properly secured.
