- Exact-Fit Replacement — engineered to match the original tool supplied with the machine, so it seats fully in recessed bolt heads without slippage or rounding
- Broad DS-Series Compatibility — fits the DS50, DS50AT, DS50ATS, DS50GYRO, and DS70 concrete core drill stands, covering multiple configurations within the DS family
- Correct Torque Delivery — proper hex engagement ensures fasteners are tightened to the right torque without damaging bolt heads, protecting the integrity of critical drill stand assemblies
- Verified Part Number — ordering by part number 544279801 confirms you receive the right tool for your specific Husqvarna drill stand, eliminating guesswork during service
A hex key is the correct-fit drive tool used to tighten, loosen, and adjust socket-head cap screws and set screws found throughout a core drill stand assembly. Using the right hex key — one that matches the exact socket size and is hardened to an appropriate grade — prevents rounding of fastener heads and ensures joints are secured to the correct torque. An ill-fitting or worn substitute tool can strip fastener heads and compromise the structural integrity of the stand, leading to misalignment during drilling or unsafe operating conditions.
