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.
Open-end and Flat Wrenches. The most basic type of wrench, open-end and flat wrenches have open jaws that slip onto nuts and bolts. Because they can be slim and short, these wrenches are especially useful in tight spaces. They’re not adjustable, so they’re sold in wrench sets of all sizes. They’re available in both SAE sizes, which are expressed in fractions of an inch, and in metric sizes.

Grip – Impact wrenches can actually come in a few shapes and sizes, but in this guide we’ve concentrated on models that – if you squint – look like standard power drills. We’ve done this as most cordless style impact wrenches are of this type. They are also simple to use. Because of their shape they do need a good grip, so make sure you bear that in mind. A good grip should be ergonomic, so it’s comfortable to hold, with good trigger placement and a raised or rubberized surface so you can orient the tool in your hand by touch only.

Was anemic at best, 500 ftlbs rating, apparently not on the one I purchased. The metal housing between the CH logo and the socket connection nub is forms sheet steel. Not a cast alum like on a normal impact hammer, so if you drop this more than 12'' onto concrete, it bends the thin metal housing and the tool no longer rotates. Either install padding and carpet in your garage, or look for another tool.

If someone or something throws a wrench into the works or throws a monkey wrench into the works, they cause problems which prevent something from happening in the way that was planned. Of course they may not sign the agreement by the sixteenth and that would throw a monkey wrench into the works. Note: Instead of saying the works, people often describe the situation in which the problem is caused. Most health-related problems, of course, are not life-threatening, but they can throw a wrench into an otherwise pleasant holiday. The US delegation threw a giant monkey wrench into the process this week by raising all sorts of petty objections. Note: The usual British expression is throw a spanner in the works.

If you have the Matco MCL2012HPIWK impact wrench, then you should be proud of it. It won’t leave someone stranded by not doing work. In fact, when using the Matco Tools impact, it felt like it hit the hardest initially when removing a fastener, and this showed in our speed test. It does lack in the total power department, but that’s not the real reason this impact finished in 8th place.
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.

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

tappet wrench ? A spanner of small to moderate size constructed similarly to an open ended wrench, but with a thinner cross section. Its purpose is to apply torque to the fasteners found on the valve trains of older engines, especially automobile engines, where the valve train required adjustment of the tappets (also known as lifters). Tappets, push rods, rocker arms and similar adjustable pieces are often equipped with locknuts which are thinner than standard nuts, due to space limitations. Frequently, the hex section of the adjustment is contiguous to the lock nut, thus requiring a thinner "tappet wrench" to be used. specialty
