- Service Accuracy — Using the correct OEM hex key protects fastener heads and threaded bores, preventing damage to drill components during assembly, disassembly, and adjustment.
- Cross-Reference Confidence — Verify part number 525437601 against your Husqvarna parts diagram to confirm this is the right tool for your specific machine configuration before servicing.
A hex key is the dedicated service tool used to drive internal hex fasteners — also known as Allen-head bolts and set screws — found throughout the assembly and adjustment points of Husqvarna concrete core drills. Using the correct hex key ensures full contact with the fastener socket, which prevents rounding of the drive recess and protects threaded components from being over-torqued or damaged. When the wrong size or a worn tool is used, fastener heads can strip, making disassembly difficult and potentially causing costly damage to the drill motor or stand hardware. This genuine OEM hex key eliminates that risk by providing the exact size and engagement geometry Husqvarna specifies for these machines.
