The Wacker Neuson Nut.500-13 Hex Jam Zinc is a genuine OEM fastener designed for the G-Series line of portable and skid-mounted mobile generators. As a direct OEM replacement, this zinc-plated jam nut delivers the same thread specification, dimensional tolerancing, and corrosion resistance as the original hardware. It fits an extensive range of G-Series generator configurations — including the G25, G50, G70, G85, G120, G125, G150, G160, G180, G230, G240, and G320 series — covering standard, cold weather, and custom variants across multiple Tier ratings. Sourcing as a genuine Wacker Neuson part ensures you are reinstalling hardware that meets the exact specification of the original build.
Key Features
- Zinc-Plated Corrosion Resistance — The zinc coating guards against rust and oxidation, making this fastener well-suited for outdoor generator installations and variable weather environments.
- Correct Thread Engagement — Sized at .500-13 UNC, this jam nut threads directly onto matching fasteners with no reworking of hardware or mating components.
- Genuine OEM Part — Manufactured to Wacker Neuson's original hardware specification, confirming consistent clamping load and thread fit across every application where this nut is used.
- Broad G-Series Generator Coverage — Confirmed fitment across the G25, G50, G70, G85, G120, G125, G150, G160, G180, G230, G240, and G320 generator families, including skid-mount, cold weather, and custom Tier 3/T4i/T4 Final configurations.
- Structural Locking Function — A jam nut used in the correct position locks an adjacent fastener against loosening from vibration — critical on generator frames and mounting assemblies that experience continuous operational vibration.
A hex jam nut is a thin-profile nut threaded onto a bolt or stud and tightened against a primary nut or component face to lock the assembly in place. On generator equipment like the Wacker Neuson G-Series, jam nuts are used in frame, mounting, and enclosure hardware where vibration would otherwise allow fasteners to back off over time. When a jam nut is missing, damaged, or the wrong thread size, the fastener joint loses its locking action and the assembly can work loose during operation — leading to misalignment, mechanical wear, or structural failure of the affected mount.
