Torque Wrenches. A torque wrench allows you to apply a precise measure of force, or torque, to a bolt. Use these wrenches when you need to tighten bolts an exact amount, such as in engine repair. Some models have a scale that indicates the torque. Others create a clicking sound when the desired torque is reached. You can also find options with digital readouts for extra precision. 
It’s not all about power. While power and performance play into our formula, we also take into account value, ergonomics, features, and more. In the end, our charts, in-use photography, and videos should validate the objective results that determine the outcome. Okay, we know our audience, and we know what you want. We’ll keep from dilly-dallying any longer, and we’ll start with the knockout punch, right out of the gate.

crow's-foot spanner A wrench that is used for gripping the nuts on the ends of tubes. It is similar to a box-end wrench but, instead of encircling the nut completely, it has a narrow opening just wide enough to allow the wrench to fit over the tube, and thick jaws to increase the contact area with the nut. This allows for maximum contact on plumbing nuts, which are typically softer metals and therefore more prone to damage from open-ended wrenches. common
Once you have the wrenches you need, you'll need to keep them organized. Sears carries a number of specific organizers to help you keep your wrench sets in one place. They can be hung on the wall or placed in a tray that can slide into a drawer. Customize your wrench storage to fit your working style as well as your workshop layout. Get all the wrenches you need to complete any job.
Where the Ingersoll Rand did suffer a bit is in the feature set area. This is where the age of the tool showed. There is no worklight, it’s only a single speed/mode, and it has a brushed motor. We would love to see a remake of this gun, using the great features as in our review of the Ingersoll Rand W5132 Cordless Impact Review. If Ingersoll Rand will release a new 1/2” high torque, with a brushless motor, multi-speed features, and the halo LED worklight, then first place may be much closer.
speed brace A crank-shaped handle that drives a socket. The socket-driving analog of the brace used to drive a drill bit. Used instead of a ratchet in a few contexts when it can save substantial time and effort—that is, when there is a lot of turning to be done (many fasteners), ample room to swing the handle, ample access to the fastener heads, etc. Has less leverage than a conventional ratchet wrench. Used occasionally in automotive repair or job shop work. socket
An impact wrench can be an extremely useful tool in the armoury of any at home mechanic. After all, we’ve all encountered that rusty bolt that simply refuses to shift, or that upgrade project that needs us to remove and replace about 15,000 bolts. There is however a better way to tackle these jobs that doesn’t result in skinned, bleeding knuckles, tears, tantrums and wrenches thrown through windows.

The Makita XWT08Z LXT High Torque is a great investment for anyone who needs to do some heavy duty work and is one of the best of its kind. The device is powered by a strong brushless motor that allows it to work harder than other competitive models while maintaining cooler core temperatures. The motor also proves to be energy efficient and can improve the battery run time by up to 50%. You’ll be able to choose from three different speed settings that can attain speeds of up to 2,200 rpm and be able to do some serious work with the power output.

Look for design enhancements, such as all-metal construction for the gear housing or high-strength plastic overmolds, which helps to prevent damage due to impacts or being dropped. Impact wrenches with brushless motors have fewer moving parts, which means that there’s less of a chance of components breaking down, and maintenance is easier to perform.
Size is usually designated by dimensions such as across-flats distance (inscribed-hexagon size). In the 19th and early 20th centuries, it had been common to define the nominal size of the wrench according to the nominal size of the screw thread that it was meant to be used with. Modern practice uses a size designation based on across-flats distance, whether measured in metric or in inch units.

Over the past two decades we've tested hundreds of tools, but we never ran a competition this close. First, we tightened 38-inch and ¾-inch nuts with a torque wrench. Then we gathered seven cordless impact wrenches and removed the nuts. Somehow there wasn't a single tool with which we had a substantial complaint. We even tried it blindfolded, and could barely differentiate among our top performers. We chose our winner based on subjective measures: how it handled, balance, and grip. In terms of pure performance, though, the 41/2-star machines are just as good. Tools have come a long way in twenty years.
With a corded electric impact wrench, you just plug it in and turn it on. Slip on the socket and extension and you’re ready to rock. An electric impact wrench can prove be one of the go-to tools in your shop that allows you to fly through difficult jobs. Just keep in mind that corded electrics won’t have the nut-breaking torque of an air tool. Fair enough.
Shopping online for impact wrenches puts the largest selection at your disposal. The first consideration to make when shopping for an impact wrench is the size you need. An impact wrench can have just about any standard socket-wrench size, with models as small as 1/4 inch all the way to over 3 inches. Choose the size that you would most commonly use.
And if the lug nut is in a position that is frequently exposed to the elements – especially water – you’ll have to take into consideration the possibility that your lug nut could quite possibly rust over and cause some major problems for you. In any of the above situations, you’re going to need a lot more torque power to get the lug nut out than it took to put it in originally.
