The Wacker Neuson Lock Washer M8 is a genuine OEM fastening component designed for the G-Series portable generator line and CRT48 ride-on trowel. This small but critical hardware piece ships direct from the Wacker Neuson parts catalog, ensuring the correct material grade and dimensional spec every time. It fits an extensive range of G-Series models including the G20, G25, G40, G50, G60, G70, G85, G150, G180, G230, G240, and the CRT48-31V ride-on trowel variants. When you need an exact match to the original hardware, part number is the correct genuine OEM choice.
Key Features
- Genuine OEM Hardened Construction — Manufactured to the same material hardness and surface treatment spec as the original factory hardware, so it bites and holds under torque the way it was engineered to.
- M8 Thread Compatibility — Sized precisely for M8 fastener applications; drops onto the bolt shank and seats flush against the mating surface without filing or shimming.
- Broad G-Series Generator Coverage — Verified fit across G20 through G240 skid-mounted and mobile generator configurations, including standard, cold weather, extended run, and custom variants.
- CRT48-31V Ride-On Trowel Fitment — Also confirmed for CRT48-31V-H, CRT48-31V-E, CRT48-31V-ES, and CRT48-31V-ES-E trowel configurations.
- Prevents Fastener Back-Off — A lock washer that has lost its tension or deformed allows bolted connections to work loose under vibration — replacing it restores the clamping integrity of the joint.
A lock washer is a thin, hardened ring installed between a bolt head or nut and the mating surface to resist rotational loosening caused by vibration or dynamic loading. The spring tension built into the washer bites into both the fastener and the surface beneath it, creating resistance that keeps the joint tight during operation. When a lock washer is flattened, corroded, or missing entirely, the fastener it secures can gradually back out, potentially causing loose panels, covers, mounting brackets, or electrical connection points to shift — leading to accelerated wear on surrounding components or loss of a secure ground or structural connection.
