Key Features

• OEM Thread and Torque Specification — Manufactured to Husqvarna's exact thread pitch and prevailing-torque rating, so the nut locks and holds as designed without under- or over-tightening.
• Drop-In Replacement — Matches the original fastener geometry, allowing straightforward installation without reworking the mating hardware or adjacent components.
• Broad Cross-Equipment Fitment — Fits a wide range of Husqvarna construction equipment including FS-series floor saws, WS-series wall saws, K-series power cutters, PP-series power packs, PG and HTC floor grinders, TS and MS tile and masonry saws, and more.
• Locking Retention Under Vibration — The hexagon locking nut's prevailing-torque design resists loosening caused by operational vibration, helping maintain the integrity of the assembly it secures.
• Genuine Husqvarna OEM Part — Supplied as an authentic Husqvarna component, not a generic fastener substitute, so material grade and dimensional tolerances meet the original design intent.

A hexagon locking nut is a fastener designed to resist self-loosening under vibration and dynamic loads — conditions that are common in cutting, grinding, and compaction equipment. Unlike a standard hex nut, the locking version incorporates a prevailing-torque feature, such as a nylon insert or deformed thread section, that creates resistance against rotation even when the joint is subject to repeated shock or oscillation. A loose or missing locking nut can allow components to shift out of alignment, accelerate wear on surrounding parts, or create an unsafe operating condition, making correct hardware replacement important whenever an assembly is disturbed during service.
