The hollowcore allow for the bolt to pass all the way through the nut driver and exit the bottom of the handle. This works well for longer applications. Whereas the hollow shaft only allows a depth of roughly 3" before stopping inside of the handle.

Customer Reviews

Rated 4.7 out of 5 by 7 reviewers.
Rated 5.0 out of 5.0 by top notch These drivers are a major upgrade from your typical set of cheap nut drivers with little colored plastic handles. These have really big, comfortable grips and you can apply some serious torque. The markings are easy to read and if you like colors, they're also color-coded on the ends. They have hollow shafts so you can slip them down over a bolt of any length. The attached photo shows an example of how this can be very handy, when you need to spin a nut some distance - much easier than flipping a wrench around and around. November 29, 2013
Rated 5.0 out of 5.0 by Perfect all thread tool I am a plumber, usually we use small channel locks or a box wrench for all thread nuts. With this you can easily tighten the nuts but the best part is you can why more easily start the nuts, anyone who uses all thread knows when you cut the rod, every so often you get the price with a burr on it and hand starting the nut drives you crazy. With this nut driver it makes it easy, and the magnet prevents you from dropping the nut off the ladder. Every one in commercial construction needs this. Especially the 9/16 one for 1/2 inch nuts on 3/8 all thread. September 7, 2015
Rated 5.0 out of 5.0 by BEST Nut Drive Set...Period! I've been using various nut drive sets for the past 40 years...this Milwaukee set is the BEST! Very solidly built, wonderful ergonomics and plenty of features. I'll now be able to grab this set for use on several different fastener configurations...Nice! When I have a need for a deep fitting adjustment, these solid "hollowcore" nut drivers will get-er-done! I would like to have had a case included, but not really a deal breaker. The lifetime warranty is also very nice, but feel I'll never need to use it...these should last me a lifetime! April 5, 2014
Rated 3.0 out of 5.0 by Good tools, NOT for HVAC use I purchased these nut drivers for HVAC use, where we constantly install and remove hex head screws. I quickly discovered these were not designed for this purpose. The splines are set to far back from the end of the nut driver, making very hard to get a grip on most hex head screws. Also, the depth of the socket is much deeper than any other nut driver I've owned, which then sets the magnet too far back to grab hex head screw. On the flip side, I'm sure this design is great for actually turning nuts and bolts, and the pass through design is great for threaded rod. It's just not the primary use I purchased them for.

Rated 5.0 out of 5.0 by Top Of The Line Nut Drivers This Milwaukee Nut Driver Set has some very nice features that sets it apart form others:: - The twelve point ends allow you to use these on nonstandard nuts or screws like square head screws. - The ends are also magnetic and nice and strong. You won’t drop the screw or nut when you are in difficult places. - Hollow shafts and handles make tightening bolts of any length possible. - Rubber grips on the handles are comfortable and allow for a better grip for tightening. - Hex shanks are great and you can use an adjustable wrench on them for extra tightening. - The Lifetime Warranty speaks for itself. There are no negatives and I really don’t see any opportunities for improvement on the set. Please view the video that demonstrates the ability of these nut drivers to tighten square head screws and and please note the extra strong magnetic ends and how well they secure screws.

Rated 5.0 out of 5.0 by Incredibly useful Very easy to use when you can't fit a wrench to tighten a nut down no matter the length of the bolt or all-thread. Very good buy. February 18, 2014
Rated 5.0 out of 5.0 by Awesome Product Really great quailty and a time saver for small projects. The feel in your hand is better than any I have experienced. December 6, 2013
