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.

I bought this on a whim when I walked by it at my neighborhood Denver Walmart. I am a professional mechanic, and this tool has been perfect for light to heavy workload. Using it in a shop where I need it for at least ten cars a day, It works great for every task, especially taking lug nuts off of wheels. I did break it within a year, however, which is Campbell Hausfeld's factory warranty, and I contacted them and I got a completely free replacement, and really great service in the process. No, it's not the absolute best impact wrench, but it is worth much more than the price, as I have had many other brands for way too much money, and this one beats all of them that were worth even up to 300 bucks. Above all, the service and the warranty were the best parts of my experience, and I highly recommend it.

Two wrenches, both nominal size ​5⁄8 in, with a diagram superimposed to show the logic that allows them both to be labeled the same when their actual sizes are clearly different (across-flats distance vs screw diameter). The larger wrench in this photo is from the 1920s or earlier; its face was polished to allow the size stamp to be visible in the photograph.

Regardless of the style of cordless impact wrench that you choose, or what its socket size is, the most important feature to consider is how much torque it generates. When performing a cordless impact wrench comparison, look at the maximum torque that each one is capable of creating. Many of the best cordless impact wrenches feature multiple torque settings making them much more versatile than those with only one torque setting. Setting he torque down only to what’s needed lets your battery work longer and prevents overtightening.
flogging spanner This is a specialized thick, short, stocky wrench with a block end to the handle specifically designed for use with a hammer, enabling one to impart great force. Used commonly with large fasteners, especially a nut and stud which both have index marks: the nut is screwed hand-tight, then further tightened with the striking wrench a known number of index marks calculated from the elasticity of the bolt or stud, thus giving precise torque (preload). Striking wrenches also provide shock and high force used to release large and/or stuck nuts and bolts; and when space does not allow room for a large wrench. common

L wrench Allen key A wrench used to turn screw or bolt heads designed with a hexagonal socket (recess) to receive the wrench. The wrenches come in two common forms: L-shaped and T-handles. The L-shaped wrenches are formed from hexagonal wire stock, while the T-handles are the same hex wire stock with a metal or plastic handle attached to the end. There are also indexable-driver-bits that can be used in indexable screwdrivers. keys
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.
If you really (Really) need brute force, look at this Air Cat Nitro Cat. It delivers an amazing 1,000 blows-per-minute delivering all the speed of a 1/2-inch drive tool with 3/4-inch drive power. They are engineered with the Extreme hard-hitting, twin-clutch mechanism. The housing is aramid-reinforced and it keeps the weight at only 4.7 pounds. By the way, it has a torque rating of (get this) 950 foot-pounds. (Image/Summit Racing)

box-end wrench ring spanner A one-piece wrench with an enclosed opening that grips the faces of the bolt or nut. The recess is generally a six-point or twelve-point opening for use with nuts or bolt heads with a hexagonal shape. The twelve-point fits onto the fastening at twice as many angles, an advantage where swing is limited. Eight-point wrenches are also made for square-shaped nuts and bolt heads. Ring spanners are often double-ended and usually with offset handles to improve access to the nut or bolt. common

Many mechanics probably have the MAC Tools BWP151 in their tool arsenal, and rightly so. This is a very powerful impact gun, and it shows. In the end, the MAC BWP151 finished with 81.4 points in our shootout. In the power category, it and the DeWALT finished neck and neck, in 3rd and 4th place, so it delivers plenty of power. The MAC Tools impact should have done much better in our speed (repetitive power) testing, but it seemed to have a fraction of a second longer lag, from the time you pull the trigger until the gun starts.
Power or impact wrenches are used for tightening or loosening nuts quickly. They are essentially small handheld electric or pneumatic motors that can rotate socket wrenches at high speed. They are equipped with a torque-limiting device that will stop the rotation of the socket wrench when a preset torque is reached. Pneumatic wrenches are commonly used in automobile service stations, where compressed air is available and the sparking of electric motors is a fire hazard.

A total length of barely 5 inches and a weight of less than 3 pounds means this tool is one of the few things around that is actually smaller than your Dad’s… ego. Jokes aside, if you need a tool to fit into tight spaces, this could be the one for you. It also boasts a comfortable ergonomic grip, a 3x speed power selector for effective control and the brushless engine we like to see.
Automotive repair shops each have their own unique selection of tools, but almost all have one tool in common: the impact wrench. An impact wrench, which may also be called an air gun, air wrench, or torque gun, is a power tool that puts a high-torque output in the palm of your hand, without much work on your part. Rather than tightening a bolt by hand, which would not give you enough torque to ensure it was completely tight and safe, you can use an impact wrench to torque it and ensure it is tight. The wrenches have a socket wrench design, which is often used to repair automobiles and other heavy equipment. It can also be used in construction projects or product assembly when the products are large and heavy.
Sockets and extensions for impact wrenches are made of high tensile metal, as any spring effect will greatly reduce the torque available at the fastener. Even so, the use of multiple extensions, universal joints, and so forth will weaken the impacts, and the operator needs to minimize their use. Using non-impact sockets or accessories with an impact wrench will often result in bending, fracturing, or otherwise damaging the accessory, as most are not capable of withstanding the sudden high torque of an impact tool, and can result in stripping the head on the fastener. Non-impact sockets and accessories are made of a harder more brittle metal. Safety glasses should always be worn when working with impact tools, as the strong impacts can generate high-speed shrapnel if a socket, accessory, or fastener fails.
