Klein Tools 32596 8-in-1 HVAC Slide Drive Screwdriver/Nut Driver

Introducing the Klein Tools 32596 8-in-1 HVAC Slide Drive Screwdriver / Nut Driver—a compact, purpose-built tool designed for HVAC technicians who value versatility and reliability on the job. The standout feature is a unique, patented head that slides to switch between 1/4-inch and 5/16-inch magnetic hex heads, letting you adapt quickly without swapping tools. The tool also offers a thumb nut that locks the tip setting, so you can maintain your chosen configuration while you work. From thermostat wiring to control panel adjustments, this tool aims to streamline several common tasks in a single handle.

The 8-in-1 design integrates hollow nut drivers for 1/4-inch and 3/8-inch sizes, plus a set of screw tips that include a #2 Phillips and slotted tips in 1/8-inch (3 mm) and 1/4-inch (6 mm). The combination of magnetic retention and hollow drivers helps you keep fasteners from dropping in tight spaces and reduces the number of trips to your parts tray. A Cushioned Grip handle provides comfort and greater torque, helping you maintain control even when you’re working in awkward angles or overhead.
