  • Klein 605-6 Screwdriver: My Go-To HVAC Tool

    ByMike Izzo

    After twenty years turning screws in cramped attic spaces and frozen crawlspaces, I’ve learned that your screwdriver either earns its spot in your pouch or it doesn’t. The Klein 605-6 earned mine on day one.

    This isn’t some imported knockoff that’ll twist on you mid-job. It’s USA-made steel that bites into screws like it means business. The 6-inch shaft gives you enough reach for those recessed panel screws without being so long it catches on everything. The cabinet tip fits terminal screws perfectly-no cam-out, no stripped heads.

    I’ve dropped this thing off ladders, used it as a mini pry bar (don’t tell Klein), and it’s still perfectly straight. The cushion grip actually stays put when your hands are greasy. At this price point, there’s simply no reason to carry anything else for electrical work.

  • Klein 32314: My Go-To Precision Driver for HVAC

    ByMike Izzo

    After fifteen years crawling through attics and squeezing into mechanical rooms, I’ve learned that cheap multi-tools are just expensive mistakes. The Klein 32314 changed how I handle precision work on control boards and thermostats. What sets this apart isn’t just the 14-in-1 design—it’s that Klein actually understands what “precision” means in the field. The tamperproof TORX bits handle modern equipment without stripping, and those nut drivers are genuinely useful for valve packing and small fittings. The electronic handle is solid enough that I’m not babying it, yet balanced for detailed work when I’m troubleshooting a condensate pump at arm’s length. It’s become the first tool I grab for any electronic component work. Not the cheapest option out there, but it’s paid for itself dozens of times over.
