  • Awesome tools
Style: Non-Magentic
I work in refrigeration and deal with a lot of different things, but these nut drivers are awesome, have had them for around 2 years and they are still in good condition. I like the hallow shaft to allow you to remove a nut that is on a long bolt. Would recommend

  • Very pleased with this set of drivers.
Style: Non-Magentic
They're Klein, and that typically means quality tools and this set doesn't disappoint. I keep the set in my Veto MCT bag which lives in my van and I only pull it out on big jobs. I think what sets Klein apart is the color and sizes on the handle tips, makes them easy to identify and pull from the bag. Quality is just superb and I like that the shank is hollow. Couple weeks ago was working in a cooler and had to replace a little evaporator blower fan. I grabbed the MCT bag and used this driver set because nothing else was going to make quicker work of it than these. The set offers up the majority of sizes that I'll ever run into so for me it was perfect. If your looking for a great starter set, new to the HVAC trade like I was when I purchased this is a great set to go with. Keep in mind this isn't the set with the magnetic tips, this is the hollow shank type which is very useful for removing nuts on bolts that are very long. ... show more

  • Actually made in the USA, and they’re excellent quality. Worth it for sure.
Style: Non-Magentic
The title sums it up. I’ve been trying to buy more American made products to support our manufacturing jobs. These tools are made really well, and I’m very impressed with the quality. Definitely worth the extra 10 minutes of research.
