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
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.
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)
Cordless impact wrenches come in two body styles: inline and pistol-grip. The inline style of impact wrench looks a lot like a large screwdriver, with a grip behind the hammer and anvil. The pistol style is shaped like a handgun, and the grip rests underneath the motor. Cordless impact wrenches also feature a selection of socket sizes designed to fit nuts and bolts of different sizes. The following table shows what socket sizes work with each impact wrench shape. Inline wrenches work best for jobs where you’re working in tight spaces and simply can’t fit a pistol-type impact wrench. If you plan to work on machinery, especially cars, then an inline impact wrench is a must-have tool.

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.
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.
Yet another design uses a rocking weight inside the hammer, and a single, long protrusion on the side of the anvil's shaft. When the hammer spins, the rocking weight first contacts the anvil on the opposite side than used to drive the anvil, nudging the weight into position for the impact. As the hammer spins further, the weight hits the side of the anvil, transferring the hammer's and its own energy to the output, then rocks back to the other side. This design also has the advantage of hammering only once per revolution, as well as its simplicity, but has the disadvantage of making the tool vibrate as the rocking weight acts as an eccentric, and can be less tolerant of running the tool with low input power. To help combat the vibration and uneven drive, sometimes two of these hammers are placed in line with each other, at 180° offsets, both striking at the same time.
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.

Old English wrencan "to twist," from Proto-Germanic *wrankijanan (cf. Old High German renken, German renken "to twist, wrench," Old English wringan "to wring"), from PIE *wreng- "to turn" (cf. Sanskrit vrnakti "turns, twists," Lithuanian rengtis "to grow crooked, to writhe"), nasalized variant of *werg- "to turn" (cf. Latin vergere "to turn, tend toward"), from root *wer- (3) "to turn, bend" (see versus). Related: Wrenched, wrenching.

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.
