The Husqvarna 505731001 Lock Washer 3/8 Split Stainless Steel is a genuine OEM component designed for the SoffCut2500 and SoffCut5000 early entry saws. As a direct OEM replacement, this washer meets Husqvarna's material and dimensional specifications, ensuring correct clamping force and corrosion resistance in demanding concrete cutting environments. DHS Equipment supplies this part to help keep your equipment running at full capability.
Key Features
- Stainless Steel Construction — Resists corrosion and oxidation in wet concrete slurry environments, maintaining structural integrity over repeated use cycles.
- Split-Ring Locking Design — The split profile bites into mating surfaces under torque load, preventing fastener loosening from vibration common in early entry saw operation.
- Genuine OEM Specification — Manufactured to Husqvarna's exact 3/8 dimensional tolerances, ensuring correct seating and consistent clamping load on the target fastener assembly.
- Direct Replacement Fit — Engineered to install directly in place of the original hardware on SoffCut2500 and SoffCut5000 early entry saws with no modification to surrounding components.
- Fastener Integrity Under Vibration — Early entry saws generate sustained vibration during green-concrete cutting; a properly functioning split lock washer maintains critical fastener tension throughout the cut.
A split lock washer is a hardened ring with a single break and a slight helical twist that creates spring tension when a fastener is tightened. This tension applies continuous clamping force against the nut or bolt head, resisting the loosening effect of vibration and cyclic loading during machine operation. When a lock washer is worn flat, corroded, or missing, fasteners can back out over time, leading to loose assemblies, misalignment, and potential component damage on the saw.
