Key Features
- Genuine OEM Material Grade — Manufactured to Husqvarna's original hardness and temper specifications, so the locking tension matches what the fastener assembly was engineered to hold.
- Exact Dimensional Fit — Matches the original bore size, outer diameter, and thickness of the factory washer, dropping directly onto the correct fastener without any modification to surrounding hardware.
- Confirmed Wall Saw Compatibility — Verified fitment for the WS220 and WS8 wall saws, two of Husqvarna's core track-mounted cutting systems used in concrete and masonry applications.
- Fastener Retention Under Load — A correctly functioning lock washer resists fastener back-out caused by vibration during cutting. A worn or missing washer allows critical fasteners to loosen, which can affect track alignment and cutting accuracy.
A lock washer is a thin hardened ring installed beneath a nut or bolt head to prevent the fastener from loosening under vibration and dynamic load. In a wall saw like the WS220 or WS8, high-frequency cutting vibration is transmitted through the track and carriage assembly, placing constant stress on every fastener in the system. When a lock washer loses its tension or deforms, fasteners can work loose progressively, leading to play in critical joints, misalignment of the cutting head, and potential structural failure of the assembly. Replacing a damaged or missing lock washer with the correct OEM part restores the clamping integrity the assembly depends on.
