crow's-foot wrench crow's foot A type of wrench designed to use the same drive sizes as socket wrenches, but non-cylindrical in shape. The ends are the same as those found on the open-end, box-end, or the flare-nut wrenches. These wrenches are used when torque must be measured, or when the application precludes the use of a regular socket or wrench. Also used in place of conventional open/box wrenches where the wrenches are large, usually at a lower cost, or for when space and weight restrictions are critical. socket

	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

In North American English, wrench is the standard term. The most common shapes are called open-end wrench and box-end wrench. In American English, spanner refers to a specialised wrench with a series of pins or tabs around the circumference. (These pins or tabs fit into the holes or notches cut into the object to be turned.) In American commerce, such a wrench may be called a spanner wrench to distinguish it from the British sense of spanner.

We love the DEWALT DCF880HM2 for its simple yet easy to use design and ability to make work easier. It comes with an impressive energy efficiency system that allows you to have 33% more charge than other standard battery packs are capable of attaining. This translates into about 24 hours of work time that you’ll be able to use before the batteries need to be recharged again. You’ll also be able to take advantage of the hog ring anvil incorporated into the design. It makes it easier to do socket changes and get on to other work.


cone wrench cone spanner A thin open-end wrench used to fit narrow wrench flats of adjustable bearing bicycle hubs. Called a "cone" wrench because it fits wrench flats of the cone section of a "cup and cone" hub, this tool is also used with some other adjustable hub bearings. The wrench is very thin so has little strength; to compensate, cone wrenches typically have a large head. Most bicycle front hubs use a 13 mm; most rears use 15 mm. specialty
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.
clamp ratchet wrench clamp ratchet spanner An open-ended multi-size ratchet wrench. The ratcheting mechanism allows the nut to be clamped-on or loosened with a reciprocating motion; flip the wrench to change direction of the drive. The wrench takes the advantage of the clamp action to allow multiple sizes in both SAE and metric standards. Each wrench typically will allow up to 3 non-metric sizes and 3 metric sizes. adjustable

I bought this to work on my van. I could not get 100 + foot pounds out of it. I put 150 pounds of air into it. And all I got was 80 pounds to the lug nuts. I had used a tork wrench and hand do 110 foot pounds on the lugs. Very poor instructions there's a book in 4 lanuges so this is sold as a world marquet product. I bought a 3" cut off tool also haven't used it yet.
Great comparison test, better than the others I read online. I ended up buying the first gen Milwaukee, which is still a great gun. I used a co-workers and was impressed pulling lug nuts off a one-ton dump truck. I was able to get the gun, hard case, set of Milwaukee-branded impact sockets, two 5.0Ah batteries, the charger, gun nose protection boot, and Milwaukee LED worklight for $450. Too good a deal to pass up.
The Milwaukee 2763 has very few notable faults. One issue is that the work light LED is just under the front of the impact. Commonly, users will use their other hand to brace the front of the impact, this will block the LED so it’s nearly useless. The 2763 delivers great power, and it did well in our speed test as well. Milwaukee sets itself apart with the 5-year warranty, and you can buy it online, your tool store, or in the big box stores.

Leading the pack in driving the weight up the scale is the Milwaukee 2767 (Gen 2) cordless impact wrench. While all the others can’t max the scale with 50-pounds atop, the 2767 can. In fact, we had to add 10 more pounds, a total of 60, and the Milwaukee 2767 still drove it the majority of the way. DeWALT and the Ingersoll Rand followed a pretty close second at 94% and 92% of the Milwaukee in the power category.
There are many reviews and head-to-head impact wrench tests that already exist. Most of these tests include the Skidmore Wilhelm torque testing equipment. By turning a large nut, you raise the needle on the PSI gauge. Then, dividing by a factor provides a “torque” number. While these tests do a great job at validating (or not) manufacturer calculated numbers, we felt there were better ways to demonstrate raw power. In short, we weren’t satisfied with doing the same ol’ same.
However, since most lug nuts tend to sit in their position for quite some time before being removed, there are several things that must be factored into place. The first is that the lug nut could become too cold and freeze. This will affect how much power it takes to get the lug nut out of its place. There is also the chance that your lug nut could be stuck if one of the threads was broken or over-tightened the last time it was serviced.
The  Porter-Cable PCC740B is one of the best tools on the market for contractors and workers who need to be able to quickly and efficiently remove nuts and drive in bolts.

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.

Cordless impact wrenches are a great tool to use regardless – but they’re even better for people who enjoy working freely and without the restriction of a cord, or for people who need to be able to have tools that can travel with them throughout a workday. Cordless impact wrenches help to make work more convenient and an easy without sacrificing on any of the power that the air powered models are able to produce.

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.
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.
Mobility. By going cordless, you are taking that power and adding a real degree of mobility to it. Yes, there are pros and cons to corded and cordless devices, and you must ensure you get the best battery (and perhaps a pair of them) to offset the biggest negative of cordless devices. Still, the biggest plus is mobility and not having to worry about being tethered to a power outlet.

In the chancel was a twisted stone column, and the captain told us a legend about it, of course, for in the matter of legends he could not seem to restrain himself; but I do not repeat his tale because there was nothing plausible about it except that the Hero wrenched this column into its present screw-shape with his hands --just one single wrench.


As the output of an impact wrench, when hammering, is a very short impact force, the actual effective torque is difficult to measure, with several different ratings in use. As the tool delivers a fixed amount of energy with each blow, rather than a fixed torque, the actual output torque changes with the duration of the output pulse. If the output is springy or capable of absorbing energy, the impulse will simply be absorbed, and virtually no torque will ever be applied, and somewhat counter-intuitively, if the object is very springy, the wrench may actually turn backwards as the energy is delivered back to the anvil, while it is not connected to the hammer and able to spin freely.[citation needed] A wrench that is capable of freeing a rusted nut on a very large bolt may be incapable of turning a small screw mounted on a spring. "Maximum torque" is the number most often given by manufacturers, which is the instantaneous peak torque delivered if the anvil is locked into a perfectly solid object. "Working torque" is a more realistic number for continually driving a very stiff fastener. "Nut-busting torque" is often quoted, with the usual definition being that the wrench can loosen a nut tightened with the specified amount of torque in some specified time period. Accurately controlling the output torque of an impact wrench is very difficult, and even an experienced operator will have a hard time making sure a fastener is not under-tightened or over-tightened using an impact wrench. Special socket extensions are available, which take advantage of the inability of an impact wrench to work against a spring, to precisely limit the output torque. Designed with spring steel, they act as large torsion springs, flexing at their torque rating, and preventing any further torque from being applied to the fastener. Some impact wrenches designed for product assembly have a built-in torque control system, such as a built-in torsion spring and a mechanism that shuts the tool down when the given torque is exceeded. When very precise torque is required, an impact wrench is only used to snug down the fastener, with a torque wrench used for the final tightening. Due to the lack of standards when measuring the maximum torque, some manufacturers are believed to inflate their ratings, or to use measurements with little bearing on how the tool will perform in actual use.[citation needed] Many air impact wrenches incorporate a flow regulator into their design, either as a separate control or part of the reversing valve, allowing torque to be roughly limited in one or both directions, while electric tools may use a variable speed trigger for the same effect.
