Key Features
- Genuine OEM Hardware Grade — manufactured to Husqvarna's exact thread profile, dimensional tolerances, and material grade specifications for consistent clamping force and long-term holding integrity.
- Direct Drop-In Replacement — matches the original fastener specification, allowing straightforward installation without reworking or adapting surrounding components.
- Broad Core Drill Compatibility — fits the DM540i, DM540iKIT, and DM200 concrete core drills, covering both standard and kit configurations of the DM540i platform.
- Structural Connection Confidence — a correctly fitted nut maintains the rigid assembly tolerances that core drilling demands, preventing play, vibration-induced loosening, and misalignment under load.
- Verified Part Number Traceability — cross-reference part number 501558001 against your machine's parts diagram to confirm correct placement before installation.
A nut serves as a critical fastening element within the drill assembly, securing components to their correct positions and maintaining the clamping load required for safe, accurate operation. In a concrete core drill like the DM540i or DM200, fastener integrity is especially important — these machines transmit significant torque and vibration during use, and a loose or damaged nut can allow movement between components that degrades drilling precision and accelerates wear on surrounding parts. Replacing a worn or compromised nut with the correct OEM specification restores the assembly's designed clamping performance and keeps the machine operating as intended.
