The Wacker Neuson Lock Washer J10 Int Star Zp is a genuine OEM fastener component designed for the LTN6, LTW6K, LTW8K, and LTW20Z series light towers. As a direct OEM replacement, part is sourced to the same specification as the original hardware installed at the factory, ensuring correct fit across the full range of compatible Wacker Neuson light tower configurations. This washer is confirmed across an extensive range of LTN6, LTW6K, LTW8K, LTW20Z, LTV6K, LTV8K, and LTV6L light tower models, as well as select E1100 ground heater and HSH350 hydronic surface heater applications. When replacing fastener hardware, using the correct OEM part helps maintain proper clamp load and keeps assemblies performing as intended.
Key Features
- Genuine OEM Zinc-Plated Hardness — Manufactured to Wacker Neuson OEM specification with a zinc-plated (Zp) finish that resists corrosion in outdoor and all-weather light tower deployments.
- Internal Star Profile Locks Under Load — The J10 internal star tooth pattern bites into mating surfaces to resist loosening from vibration, which is critical in light tower mast and frame assemblies subject to transport and field movement.
- Direct Drop-In Replacement — Sized to the original J10 specification, this washer installs without modification alongside the existing bolt hardware in the assembly it was removed from.
- Broad Light Tower Compatibility — Confirmed fitment across LTN6C, LTN6L, LTN6K, LTN8K, LTW6K, LTW8K, LTW20Z-1, LTW20Z-3, LTV6K, LTV8K, and LTV6L series, covering both 50 Hz and 60 Hz configurations.
- Fastener Integrity Protects Structural Connections — A worn, missing, or incorrect lock washer allows fasteners to back out over time, which can compromise mast stability, electrical enclosure seals, and other load-bearing joints on the light tower.
A lock washer is a hardened fastener insert placed beneath a bolt or nut to prevent the fastener from loosening due to vibration, thermal cycling, or repeated stress. The internal star tooth design on this J10 washer creates mechanical interference between the fastener head and the clamped surface, maintaining clamp force even when the assembly experiences movement. When a lock washer is missing, damaged, or replaced with an incorrect size, fasteners in the assembly can gradually back out, potentially allowing panels, mast sections, or mounting brackets to shift — a particular concern on equipment that is trailered and repositioned regularly, as light towers are.
