Klein Tools 65064 2-in-1 Nut Driver, 1/4 and 5/16-Inch Hex Head, 8-Inch

I bought this when I was in HVAC and used it often when I wasn’t able to get a drill inside a unit. This worked excellently for the purpose I bought it for, I would recommend it to anyone who might need one.

Should have bought this 40 years ago. Indespensable. Magnetic on both 1/4 inch and 5/16 inch ends. Fast interchange by just pulling it out of the handle and switching ends. Grip is sure. Like it. It is difficult to beat Klein products. Everything I have ever bought that was Klein was Great. You won't be disappointed.

Fits nicer in my tool bag rather than having a couple nut drivers it does a good job

One of the best, most used tools for HVAC and appliance repair. It could be deeper, but the magnet is in the way. Overall, it's a great two-in-one nut driver.

The reversible shaft clicks firmly into place. It's magnetized to hold screws on the head.

This is the best nut driver you can buy. The reversible insert accepts 1/4" and 5/16" heads. They have built-in magnets that help hold a screw in place while you are inserting it and getting it started. This is more expensive than other similar tools, but the build quality is excellent and it handles the two most common sizes in a single, relatively compact tool. More solid than tools that have removable driver bits.

most all apliances have have this size hex head, unless its metric, however 5/16" is almost excactly the same size as 8mm , i shoulda got one of these years ago, perfect 2 in one nut driver

This is a great tool. I don’t have to have 2 tools to keep track of. Love that. Wish they were magnetic.

This is an excellent tool for the hands on type of person! Very good quality. The tips are reversible and it just pops in and out by pulling on it. Its a very snug fit and no issues of it getting loose or falling out ever. I've had it for quite a few months now and zero issues with it. I use it almost daily at work and highly recommend this. Its a bit heavy - which means quality and well built!

Una herramienta muy útil y multifuncional

Me gusto mucho, demasiado práctico asi ya no llevas dos desarmadores sino, solo 1 desarmador. Herramienta fundamental para los tecnicos en hvac

I use this every day on my job. I love that you can reverse the tool cutting down on extra weight in the toolbox.

As an HVAC tech I love this. Has both the most common nut driver sizes in one tool. Others have more bits but this is simple, solid and no parts to lose. Use it every day without complaint
