This set of drivers has made me very happy
5/5

Klein is known for producing high-quality products, and this set is no exception. I keep the set in my Veto MCT bag, which I keep in my van, and only use it on large jobs. I believe what distinguishes Klein is the color and size of the handle tips, which make them easy to spot and remove from the bag. The quality is excellent, and I appreciate the hollow shank. I was working in a cooler a few weeks ago and needed to replace a small evaporator fan. I snatched up the MCT bag and went to work with this driver set because nothing else was going to get the job done as quickly as these. If you're looking for a great starter set, this is a great set to go with if you're new to the HVAC trade like I was when I bought it. Keep in mind that this is not the set with the magnetic tips; instead, it is the hollow shank type, which is ideal for removing nuts from long bolts.

This is a set of legitimate tools
4/5

These have been on my wish list for a long time. br>They will fulfill my requirements. br>I like how the handle has size markings on it. br>A 1/4" square drive input is what I'd prefer to see there. br>br>The molding and finish are a little shabby, but not bad. br>br>I'd prefer a more gradual transition from the handle, where you apply more torque, to the shaft, where you can accelerate things. br>The tool has a genuine feel to it. This is a breath of fresh air in this world of pretenders.

EXCELLENT EXCELLENT EXCELLENT EXCELLENT EXCELLENT EX The following are the best nut drivers available on the market: period
5/5

They can cover long bolts because of the long tube design, which is something that most cheaper ones can't. Plus: Klein produces the best electrical tools in the world, all of which are manufactured in the United States. I paid a lot of money for both the SAE and the Metric, but so is your life, so don't risk it by doing electrical work with cheap tools.

I really like the hollow handles on these drives
5/5

The size range is ideal, and the magnetic tips are fantastic. The hollow handles add a lot of value - Threading nuts onto even the longest bolts has never been a problem for me. The grips are excellent, and the construction is sturdy. So far, my favorite nut drivers.

I finally got the whole set
5/5

I had bought a few of these nutdrivers before, but not the entire set. I decided to buy the set after using them and realizing that I needed more and more sizes as well. It was the high quality of these that drew me back to them. They have a powerful magnet that won't let go of its grip. I couldn't decide between these and the longer-shanked ones. I chose these because the longer ones wouldn't fit well in the outside pockets of my toolbag and would protrude too far. I didn't want to risk losing one of them if they fell out. br>br>I bought these and have used them a lot since then. In terms of the ones I purchased prior to these, I gave them to my father as a demonstration of the high quality and craftsmanship of these incredible tools. These may appear to be on the expensive side, but I promise you will not be disappointed and would buy them again if necessary. I appreciate your taking the time to read this. Ray.

Klein Tools remain a good investment
4/5

Klein has always produced high-quality, long-lasting tools. One of my old Klein tools finally broke while I was using it, so I bought this set to replace it. When I was trying to open a nut, the yellow transparent hard plastic broke apart. Yes, the broken screw was a 7/16. I was taken aback, but nothing, not even Klein, lasts forever. I had the tool for over a decade. I believe I got my money's worth out of it, at the very least. As you can see, I added to my Klein Tool collection.

Don't throw money away; instead, put your nut drivers to the test
3/5

Make sure you don't throw your money away. I spent more than $75 on this. In late August of 2019, the price will be 00. Today, October 20th, 2019, I discovered that the drivers are devoid of magnetic properties. When a 1/4" metal screw on the inside handler came loose and landed behind the evaporator coil, I realized what had happened. To recover the metal screw, I was fortunate that the customer had a long magnetic screw driver. Totally let down. br>br> Make sure to put your tools to the test.

They're made in the United States, and the quality is excellent
5/5

It was well worth it. It's all in the title, really. To help support American manufacturing jobs, I've been attempting to purchase more products made in the United States. These tools are extremely well-made, and I'm very pleased with them. The extra ten minutes of research were well worth it.
