Wacker Neuson 5000150294 Nut 5/16-18 Hex Jam Zinc Black

The Wacker Neuson is a genuine OEM Nut 5/16-18 Hex Jam Zinc Black designed for a wide range of Wacker Neuson G-Series portable and skid-mounted mobile generators and CRT ride-on concrete trowels. Sourced directly from Wacker Neuson, this hardware component matches the original specification installed at the factory. Compatible machines include the G25, G50, G70, G85, G120, G125, and G160 generator series, as well as the CRT36 and CRT48 ride-on trowel families. When replacing fasteners, using the correct OEM part ensures the hardware performs as intended and holds tolerances across the full service life of the machine.

Key Features

• Correct Thread Specification: — 5/16-18 UNC thread profile matches the original fastener specification, ensuring proper engagement without thread damage or cross-threading risk.
• Jam Nut Profile: — Low-profile jam nut design locks against a primary nut to resist loosening from vibration — a critical trait on power generation and concrete finishing equipment that runs under sustained load.
• Black Zinc Finish: — Black zinc coating provides corrosion resistance for hardware exposed to outdoor conditions, moisture, and concrete slurry on active job sites.
• Broad Fitment Across Two Machine Families: — Fits G-Series generators (G25 through G160, skid-mounted and mobile configurations) and CRT36 and CRT48 ride-on concrete trowels in multiple speed and steering variants.
• Genuine OEM Part: — Supplied by Wacker Neuson as an original equipment component, confirming dimensional accuracy and material grade consistent with the original hardware used in production.

A hex jam nut is a thin, low-profile fastener used in tandem with a standard hex nut to create a locking fastener pair. When tightened against each other, the two nuts generate opposing clamping forces that resist loosening caused by vibration, thermal cycling, and dynamic loads. On equipment such as generators and ride-on trowels — which produce sustained mechanical vibration during operation — loose hardware can lead to misaligned components, accelerated wear, or structural failure at fastened joints. Replacing a worn, stripped, or missing jam nut with the correct 5/16-18 specification restores the integrity of the fastened connection and prevents hardware-related service issues from developing.
