Lennox 18F05 – Klein Tools 32807MAG 7-in-1 Magnetic Nut Driver is a professional-grade multi-size hand tool designed to replace multiple nut drivers in one compact, durable solution. Built for HVAC technicians and service professionals, this tool combines magnetic and spring-retention technology to securely hold fasteners and improve efficiency on the job.

Seven interchangeable SAE sizes are integrated into a single shaft, allowing fast, one-handed driving without switching tools. Strong rare-earth magnets securely hold common nut sizes, while spring-coil retention handles larger sizes without magnets. Hollow shafts allow nuts to be driven deep onto bolts or threaded rod, making this tool ideal for tight HVAC cabinets and equipment panels. A heavy-duty handle and shaft exceed standard torque performance, and the built-in wrench-assist provides extra leverage for stubborn fasteners.

Designed to reduce tool bag weight while increasing productivity, the Klein 32807MAG is a reliable choice for installation, maintenance, and repair work across residential and commercial HVAC applications.
