An Allen key — also known as a hex key — is a hand tool used to drive socket-head bolts and set screws that require an internal hexagonal drive. On Husqvarna wall saws and automatic drill feed units, these fasteners appear throughout track mounting hardware, blade guard assemblies, and adjustment mechanisms. Using the correctly sized key prevents fastener damage and ensures components are seated and tightened to specification. The wrong size hex key can round out a fastener head, turning a simple service task into a time-consuming repair.
