- Vibration-Resistant Locking Action — The lock washer's helical design bites into mating surfaces to resist loosening caused by the continuous vibration inherent to truss screed operation.
- Sourced from Wacker Neuson — Supplied as a genuine OEM part, ensuring material grade and hardness match the original fastener assembly for consistent, long-term holding performance.
A lock washer is a hardened fastener component placed between a nut or bolt head and the mating surface to prevent the fastener from loosening over time. In vibratory equipment like the HPG Truss Screed, constant oscillation creates conditions where standard fasteners can work themselves loose, leading to structural instability, misalignment, or component damage. A worn, deformed, or missing lock washer compromises clamping force, which can allow critical assemblies to shift during operation and accelerate wear on surrounding hardware.
