Key Features
- Genuine OEM Thread Specification — manufactured to Husqvarna's exact thread pitch and torque rating, delivering the correct clamping force for each host assembly without risk of under- or over-tightening failure.
- Locking Retention Design — the lock nut's interference or nylon-lock feature resists loosening under the vibration and load cycles common to compactors, demolition robots, and floor grinders.
- Broad Cross-Family Compatibility — a single OEM part number serves the LF75PACE and LF100PACE forward plate compactors, the DXR140, DXR275, DXR305, and DXR315 demolition robots, and the PG5 floor grinder.
- Direct-Replacement Fit — matches the original fastener's dimensions and grade exactly, so the lock nut installs into the existing assembly without modification or re-drilling.
- Structural Integrity Assurance — using the correct OEM fastener maintains the designed clamping load on critical joints, preventing component shift, premature wear on mating parts, and potential structural failure in demanding demolition and compaction environments.
A lock nut is a fastener engineered to stay tight under sustained vibration, impact, and cyclical loading — conditions that would cause a standard nut to gradually back off and lose clamping force. By incorporating a locking mechanism into the nut itself, it maintains the correct preload on bolted joints throughout the service life of the assembly. When a lock nut wears out, strips, or is replaced with an incorrect fastener, the joint it secures can shift or loosen, leading to accelerated wear on surrounding components and, in high-stress applications like demolition and compaction equipment, potential safety hazards or structural damage.
