Key Features
- Genuine OEM Fastener Grade — manufactured to Husqvarna's specified thread form, head geometry, and material hardness, delivering the clamping force the assembly requires
- Direct Assembly Fit — engineered to the correct thread pitch and head profile for the target bore, so the screw seats fully without rework or modification
- Broad Core Drill Compatibility — fits DM280, DMS280, DM230, and DM340 concrete core drills, covering multiple models in Husqvarna's DM drill motor lineup
- Structural Integrity at the Connection Point — a correctly sized and properly torqued fastener maintains component alignment and prevents loosening under the vibration loads typical of core drilling
- Exact OEM Sourcing — sourced directly from Husqvarna, so the thread standard, drive type, and finish match what was installed at the factory
A screw of this type serves as a critical fastener within the core drill's assembly, securing components in position and maintaining the structural integrity of the connection under continuous operational loads. When a fastener is worn, damaged, or replaced with an incorrect substitute, it can compromise component alignment, introduce vibration-related loosening, and ultimately lead to assembly failure during use. Using the correct Husqvarna OEM fastener — part number 503200778 — ensures the joint performs as designed throughout the service life of the drill.
