Klein 32328: My Go-To Precision Screwdriver Kit
After twenty years in HVAC, I’ve learned that half my service calls involve tinkering with electronic controls and circuit boards as much as they do with compressors and coils. The Klein 32328 has become my daily driver for precision work. What sets it apart isn’t just the 27 bits—it’s that rare-earth magnet that actually holds those tiny screws from thermostats and control boards without dropping them into impossible-to-reach spaces. I’ve used it on everything from Nest installations to repairing proprietary ECM motor controllers. The apple-specific bits are a bonus for side jobs, but honestly, I reach for this tool multiple times per day on furnace boards and mini-split controls. It’s built like Klein’s regular screwdrivers, which means it’ll survive being dropped off a ladder. Worth every penny for anyone doing real fieldwork.
