Klein Tools 630-5/16 Nut Driver, Made in USA, 5/16-Inch Tip Nut Driver with 3-Inch Hollow Shaft, Cushion Grip Handle

Good quality. When I looked at the socket I though it may have been improperly made as it didn't look like a typical hex drive socket but it fit the screw hex drive perfectly.

My set of drivers topped out at 3/8”, so of course I had a project that needed 7/16”. This filled the bill and the hollow shaft was a nice bonus.

The Klein nut driver is a high quality tool. I would highly recommend Klein tools.

I bought this tool for a specific purpose an use. It does the job.

No surprise - I love Klein tools. And in my tool bag, I have all Klein tools - screwdrivers, pliers, etc. For much of my work, I find myself needing one of two different sized nut drivers. One is a 1/4in and the other is a 5/16in. I had the 1/4in, but I was missing the 5/16in - until I found this one on Amazon. Can't beat the price - shipped directly to my door - in a day or two. Seriously? Not worth driving to the big box store only to find out they're out. So now my tool bag is complete. I love the rubber handles of these Klein nut drivers. They're just like the handles on Klein screw drivers. The nut drivers have hollow shafts - perfect for long screws. And I especially like the distinct marking on the end of the handle showing the size of the nut driver. It matches my other nut driver perfectly. Looks good. Feels good. Easy to use. Works great - every time. Klein. I would definitely buy again. And I will. Thanks.

works alright , need to be straight on or will slip

I don’t know anything about tools but my dad loved them!

I have used various nut drivers previously and finally settled on Klein. I'm a plumber but, amazingly I have to go to the electrical suppliers, online or otherwise, to get the great tools. Maybe some manufacturers could wake up. Nevertheless- these are the best nut drivers I've come across. Whether performing light maintenance or large mechanical projects, this tool and others from Klein are the best for me for nut drivers.

Very reliable hand tools. 👍

Muy buen desarmador en la línea de Klein tools excelente no me arrepiento de haberlo comprado es una buena compra y por el precio está genial más aparte aquí en México pues está difícil conseguirlo en una ferretería sería mejor comprarlo por Amazon en línea
