The Wacker Neuson M4 Lock Washer is a genuine OEM fastener component designed for LTN6, LTW6K, LTW8K, and LTW20Z series light towers. Sourced directly from Wacker Neuson, this part meets the exact specifications called out in the original equipment build. It fits an extensive range of light tower configurations across the LTN and LTW families, including Kohler, Kubota, Caterpillar, and Isuzu-powered variants in both 50 Hz and 60 Hz configurations.
Key Features
- Genuine OEM Fastener Integrity — Manufactured to Wacker Neuson's exact M4 thread specification, ensuring correct clamp load and retention when torqued to spec.
- Drop-In Hardware Replacement — Matches the original M4 mounting position exactly, so installation requires no modification to existing hardware or mounting surfaces.
- Broad Light Tower Compatibility — Fits a wide range of LTN6C, LTN6L, LTN6K, LTN8K, LTW6K, LTW8K, and LTW20Z series light towers across multiple engine and voltage configurations.
- Prevents Fastener Loosening Under Vibration — The lock washer design resists self-loosening caused by engine vibration and transport movement, keeping critical assemblies securely fastened during operation.
- Electrical Safety Relevance — Used in light tower assemblies where loose fasteners near electrical components can cause arcing, shorts, or grounding failures; correct hardware matters in this application.
A lock washer is a small but essential fastener used to prevent nuts and bolts from loosening over time due to vibration, thermal cycling, or repeated movement. On light towers, where engines run for extended periods and equipment is frequently transported between job sites, fastener integrity is critical to keeping electrical panels, mast assemblies, and engine mounts secure. When a lock washer wears flat or goes missing, the associated fastener can back out gradually, leading to loose connections, structural movement, or electrical faults that are difficult to trace without a thorough inspection.
