Tighten nuts and bolts with ease.

One of the essentials you should have in your tool set is a good nut driver. A nut driver is a hand tool that you use to tighten nuts and bolts. It looks a lot like a screwdriver, but the shaft is typically hollow, at least partially, so you can thread a nut onto a bolt. Some dual-purpose tools serve as both a screwdriver and a nut driver, which can be convenient and efficient.
Don’t be confused by nut driver bits (also sometimes called nut driver drill bits or nut setters or a few other things). Although some people use all of these terms interchangeably, technically a nut driver is a manual tool, whereas nut driver bits are used with a cordless screwdriver or other power tools.
Specs to Consider
Fixed or Interchangeable Handles
Nut drivers often come in a set containing drivers of various sizes that are all attached to their own handles. But you can also choose an adjustable shaft set, which contains a single handle and an assortment of interchangeable shafts. Some people prefer full drivers because the shaft is bonded permanently to the handle, which makes it feel more stable and also prevents slipping or loosening. But a set of full drivers takes up more space and will typically cost more.
Driver Sizes
Like screwdrivers, nut drivers have a range of sizes to fit all the different nuts and bolts. The sizes you need most will depend on the types of projects you do. In my own experience, I’ve seen the 1/4-, 5/16-, 3/8-, and 1/2-inch SAE drivers and the 8- and 10-millimeter metric drivers used most frequently, but the important thing is to ensure the driver you’re considering is available in the size or sizes you need most often. Note that some sets offer a combination of both SAE and metric sizes, and others only have one type.
Shaft Length
A longer shaft (also called a shank or blade) provides more leverage but might be inconvenient when you are trying to work in cramped spaces. However, these tools are available in a wide range of lengths; again, what works best for you will depend on how and where you typically use it. I’ve most commonly seen shank lengths between 5 to 9 inches, with compact models at 4 inches or less. Keep in mind some manufacturers only list the total length of the driver without specifically listing the shank length.
How We Selected
In evaluating a variety of nut drivers to inform these recommendations, I started by considering my own experience with these tools. I’m the former owner of a construction and property maintenance business and a passionate DIYer, so I have considerable experience with both manual and power tools, including all manner of drivers and fasteners. I also studied reviews from hundreds of Amazon users and consulted manufacturer and retailer for product specifications.

The 5-in-1 Stubby Nut Driver has five drivers in sizes from 3/16- to 1/2-inch that nest inside one another within the self-contained unit. That’s convenient and saves space, because you don’t need to carry around a bunch of individual drivers. Measuring 3.5 inches from end to end, the stubby design is compact enough to fit in tight spots but might not be comfortable or preferable for everyone.

Crafted to ISO industry standards, the drivers in this 11-piece set are insulated to achieve a 1,000-volt rating and tempered for durability to ensure a long lifespan. They don’t have a hollow shaft but do have a 1-inch recessed end to accommodate longer bolts. Electricians and DIYers who regularly work with circuits won’t be disappointed should you choose to make the investment.
