Key Features
- OEM-Grade Fastener Material — Manufactured to Husqvarna's specified hardness and surface treatment, ensuring the washer maintains proper clamping force under the vibration loads typical of compaction equipment.
- Drop-In Hardware Replacement — Matches the original inside diameter, outside diameter, and tooth geometry exactly, so it seats against the mating fastener without filing, shimming, or modification.
- Confirmed Compactor Fitment — Designed for the LG300 and LG504 reversible plate compactors and the LP9505 trench roller, covering a broad range of Husqvarna light compaction applications.
- Vibration Resistance — Lock washers on compaction equipment are subjected to continuous high-frequency vibration; using the correct OEM washer preserves fastener preload and prevents progressive loosening that can lead to assembly damage.
A lock washer prevents threaded fasteners from backing out under the constant vibration generated during compaction operation. It works by biting into both the fastener face and the mating surface, maintaining clamping tension even as the machine cycles through repeated impact loads. When a lock washer is missing, worn flat, or replaced with an incorrect size, fasteners can gradually loosen, leading to component misalignment, accelerated wear on adjacent parts, or structural failure of the assembly it secures.
