Klein Tools PND91610 9/16-Inch Power Nut Driver, 10-Inch Length, Made in USA

I use this nut runner for when I'm hanging Fan Coils or Branch Selectors to seismic isolators with all thread/threaded rod. This runner is of great quality fits in the bags I carry on my person when I'm working and the magnetic tip where the nut sits is handy but you have to clean it out because it isn't always so effective since when you run a nut up or down the inside of the runner gets sort of filed a bit and the shavings accumulate on the magnet. Some butyl tape works well to clear it all out. Not really a problem but if you put a nut in the tip of the runner or you've just taken one off some all thread you need to use a piece of all thread to get it out. I've seen a piece of rubber on the Chuck of a drill works, I've even made my own 18" version with ½" conduit and quick release connection from a broken countersink rigged to the bottom and banged a few 9/16" nuts at the tip to give it shape. But this works much better.

I wish the shaft was just a hair bigger. Works great on all-thread when it's clean, but if there's butyl gasket or duct sealer on it, or if the threads are gunked up, this nut driver does tend to get hung up a bit. But, that's to be expected, really. It would just be nice to have a little bit more "forgiveness" in that particular aspect.

This nut driver is great, saves me time when I need to run conduits on ceilings are when I need to hang light fixtures. I love the fact it has a magnet to hold your bolts, especially when you're high up on the ladder and don't want to waste time to get down if you drop one. I highly recommend this for any electrician.

It does its job, but I feel cheated. Use the tool rarely and the magnet will be damaged. It seems to me to be of very low quality for a Klein tools product.

I use the heck out of this tool so it’s normal for me to break them now and again. But for the most part they hold up well especially under normal circumstances

Works great for leveling out duct work slides perfectly over 3/8” all thread so you can tighten or loosen a 9/16” nut or bolt

it's a great tool, don't get me wrong. and it's super handy when working with strut on threaded rod or even just securing 3/8 bolts into anything really...but lets be realistic, it's priced probably twice what it should be. but when you're desperate you pay it, so weigh that before buying. it's a time saver, and I love efficiency

No sabía que la necesitaba hasta que la usé, es la herramienta perfecta

Works great, has a magnet at the end so you don’t drop you nut but it’s sometimes a hindrance because it’s impossible to get the nut out within threading it back on a rod a bit. All in all great product

Recommendation

Outil parfait pour un electricien

Does not fit thru 1/4 inch redi rod

The magnet fell our right away but that doesn’t matter seeing as it didn’t hold anything anyway.
