Key Features
- OEM Thread and Torque Specification — Manufactured to Husqvarna's exact thread pitch and hardness grade, delivering the clamping force this fastener position demands across saw assemblies.
- Drop-In Replacement — Installs directly in place of the original hardware with no rework, machining, or adaptation needed to achieve a secure, properly torqued connection.
- Broad Saw Family Coverage — Compatible with the MS355, MS355G, MS510, MS510G, and MS610 masonry saws as well as the FS3500E floor saw, covering a wide range of Husqvarna cutting equipment in one part number.
- Vibration-Resistant Locking — The lock nut design resists loosening under the sustained vibration and load cycling generated during continuous masonry and concrete cutting operations.
- Structural Integrity Restored — A worn or damaged fastener compromises the integrity of the assembly it secures; replacing it with the correct OEM part restores the connection to its designed holding strength.
A lock nut is a self-retaining fastener engineered to resist loosening caused by vibration, torque fluctuation, and dynamic loads — conditions that are constant during masonry and concrete cutting work. Unlike a standard nut, the locking feature — whether a nylon insert, distorted thread, or prevailing-torque design — maintains clamping force even as the machine cycles through demanding cuts. When a lock nut is worn, cross-threaded, or missing, the assembly it secures can shift, loosen, or fail entirely, creating both a performance issue and a safety risk to the operator and equipment.
