The Wacker Neuson M5 Internal External Serrated Washer Zp is a genuine OEM fastener component designed for the LTN6 and LTN8 series light towers. As a direct OEM replacement, it meets the original design specification for the machines it serves, ensuring proper clamping force and electrical bonding where required. This washer fits an extensive range of LTN6C, LTN6L, LTN6K, LTN6LE, LTN8K, and their V-series and S-series variants, covering 50 Hz and 60 Hz configurations across standard, cold-weather, and racked builds. Ordering by part number confirms you are sourcing the correct zinc-plated M5 serrated washer for your specific light tower.
Key Features
- Genuine OEM Zinc-Plated Construction — Zinc plating provides corrosion resistance suited to outdoor light tower environments where exposure to moisture and weather is constant.
- Dual Serration Profile — Internal and external serrations grip both the bearing surface and the fastener head simultaneously, maintaining clamp load under vibration-induced loosening.
- Broad LTN Series Compatibility — Fits LTN6C, LTN6L, LTN6K, LTN6LE, LTN8K, and associated V-series and S-series variants in 50 Hz and 60 Hz configurations, including standard, cold-weather, and racked builds.
- Correct M5 Thread Engagement — Sized specifically for M5 fasteners, so it seats flush without shimming or stacking and installs directly as a like-for-like swap.
- Electrical Grounding Integrity — Serrated washers in light tower electrical assemblies play a role in maintaining secure ground connections; using the correct OEM part preserves that continuity.
A serrated washer uses hardened teeth — on the inner edge, outer edge, or both — to bite into the mating surfaces when a fastener is tightened. This biting action locks the assembly against vibration-induced loosening and, in electrical applications, cuts through surface coatings to create a reliable metal-to-metal ground contact. On light towers like the LTN6 and LTN8 series, these washers appear throughout the structure and electrical panels where both mechanical security and grounding continuity matter. A missing or incorrect washer can allow fasteners to work loose over time or introduce resistance into a ground path, both of which affect safe, consistent operation of the tower.
