Key Features
- Zinc-Plated Corrosion Resistance — The Type A zinc finish protects against rust and oxidation in outdoor and harsh-environment generator installations where moisture exposure is a constant factor.
- Serrated Bearing Surface — The serrated profile bites into mating surfaces under torque, resisting fastener loosening caused by vibration — a critical function in generator equipment subject to continuous engine vibration.
- Genuine OEM Sourcing — Manufactured to Wacker Neuson's original M16 dimensional tolerances, this washer delivers the exact load distribution and locking performance the machine was engineered around.
- Direct-Fit M16 Bore — Sized to drop straight onto M16 fasteners with no filing, shimming, or modification; reinstalls the same way the original was assembled at the factory.
- Broad Generator Fleet Coverage — A single part number covers G25, G50, G70, G100, G120, G150, G180, and G240 series mobile generators across standard, cold weather, custom, and extended run tank builds.
A serrated washer serves as a locking and load-spreading element in a bolted joint. Positioned between a fastener head or nut and the mating surface, the washer distributes clamping load across a wider area to prevent surface damage and fastener pull-through, while the serrated teeth grip both surfaces to resist the rotational loosening that mechanical vibration can cause over time. In mobile generator applications — where an engine runs for extended periods and the skid is regularly transported — maintaining tight, vibration-resistant fastener joints is essential to keeping enclosures, mounting frames, and electrical components securely in place. A worn, missing, or incorrect washer compromises joint integrity and can allow critical connections to work loose during operation or transit.
