KLEIN TOOLS631 Tool Set, Made in USA, Nut Driver Set w/Hex Nut Sizes 3/16, 1/4, 5/16, 11/32, 3/8, 7/16 and 1/2-Inch on 3-Inch Full Hollow Shaft, 7-Piece

Typical Klein quality tools. Not the least expensive out there, but if you use your tools daily these are a bargain. They also have a lifetime warranty - no questions asked replacement. This set has a wide range of sizes, comfy handles that allow a solid grip, and both labeled and color-coded as to size for a quick grab.

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.

High quality

Fantastic quality nut-drivers in a convenient set, handles are nice and grippy. Also, these won out of several other brands because the shafts are hollow, allowing them to be used over LONG studs, 3" or more. Which you never knew you needed until you just can't get to that one nut and it's 11:30PM on a Saturday and you have to drive somewhere in the morning.Only gripe: The size is marked on the end of the tools, and the markings are color coded, but when they're laying flat in a tool bag it's tough to see the markings. On some other brands I've seen, there is a color-coded band around the shaft or handle of the tool so that it can be more easily identified. But, the pros of this set far outweigh this minor con in my mind.

Handy to have in the tool bag, quality that you can expect from from Klein.

With size on end easy to see the best idea

These are quality USA made, and I can use them with my eyes closed, they are so familiar to my hand.Not hollow shaft,

These are the best nut drivers sold in the world: period. The long tube design allows them to cover long bolts which most cheaper ones can't do. Plus: Klein, the best electrical tools in the world and made in America. I bought both the SAE and Metric very expensive, but so is your life.Don't put your live on the line doing electrical work with cheap tools.
