Key Features
- Genuine OEM Hardness and Geometry — Manufactured to Husqvarna's exact material hardness and dimensional specifications, ensuring the correct spring tension and bite that a lock washer must deliver to prevent fastener loosening under vibration.
- Direct Fastener-Stack Fit — Matches the original bolt diameter, thread pitch, and bearing surface of the fastener stack it was designed for, dropping in without modification or adaptation.
- Broad Equipment Compatibility — Fits across multiple Husqvarna construction equipment families, including the DXR95 demolition robot, DM-series core drill motors, PG-series floor grinders, K-series power cutters, WS-series wall saws, and TS- and FS-series saws.
- Vibration Resistance — The serrated or spring profile of this lock washer is engineered to grip mating surfaces under cyclic loading and vibration — conditions common to cutting, drilling, and grinding equipment — keeping critical fastened joints secure during operation.
- OEM Traceability — Backed by Husqvarna's genuine parts chain, ensuring the component meets the same quality standard as the part originally installed on the machine.
A lock washer is a hardened fastening component installed beneath a nut or bolt head to prevent the fastener from backing out under vibration, dynamic loading, or thermal cycling. By biting into both the fastener and the mating surface, it maintains clamping force that would otherwise relax over time in high-vibration environments. When a lock washer fails, becomes deformed, or is missing entirely, the associated fastener can loosen progressively — leading to misaligned assemblies, accelerated wear on adjacent components, and, in severe cases, structural failures within the machine.
