The Husqvarna 505731101 Lock Washer 1/2 Split Stainless Steel is a genuine OEM component designed for the SoffCut2500 and SoffCut5000 early entry saws. This stainless steel split washer delivers the secure fastener retention these machines demand in wet, abrasive concrete-cutting environments. As a direct OEM replacement, it meets Husqvarna's original material and dimensional specifications, ensuring a correct install every time. DHS Equipment supplies this part to help keep your equipment running at full capacity.
Key Features
- Stainless Steel Construction — The corrosion-resistant stainless steel material stands up to the wet slurry and moisture exposure common in early-entry concrete cutting, maintaining holding strength where standard hardware degrades.
- Split-Lock Design — The split profile bites against mating surfaces to resist fastener loosening from vibration, a critical requirement on early entry saws operating on freshly poured concrete.
- Genuine OEM Specification — Sourced directly from Husqvarna, this washer matches the original dimensions and material grade specified for the SoffCut platform — no sizing guesswork or fitment risk.
- Compatible with SoffCut2500 and SoffCut5000 — Confirmed fitment for both the SoffCut2500 and SoffCut5000 early entry saws; cross-reference 505731101 against your parts diagram to verify the exact fastener location.
- Maintains Fastener Integrity — A worn or missing lock washer allows critical fasteners to back out under machine vibration, risking blade alignment issues and unplanned downtime. Replacing it restores the secure, vibration-resistant connection the assembly requires.
A split lock washer functions by exerting spring tension between a fastener head and the mating surface, preventing the bolt or screw from backing out under repeated vibration and load cycles. On early entry concrete saws like the SoffCut2500 and SoffCut5000, where the machine operates under continuous blade engagement and engine vibration, maintaining tight fastener connections is essential to blade tracking, guard alignment, and overall structural integrity. When this washer is damaged, deformed, or missing, fasteners can gradually loosen, compromising both machine performance and operator safety.
