Typically, a pipe wrench is composed of an upper hook jaw and a lower heel jaw, both connected to a flat handle. The lower jaw is adjustable to the size of the metal object. Forward pressure on the handle pulls the jaws closer for ease of gripping and turning. Usually made of aluminum or steel, pipe wrenches are available in various sizes measured by the length of the handle.
A wrench is an invaluable tool for general repair and maintenance. The grip and mechanical advantage it provides enables the user to apply torque to turn nuts and bolts.
When tightening a bolt to the proper torque, it is essential that your hand which is pulling the wrench is cantered on the handle of the wrench. Having it too close or far from the socket actually affects the ultimate torque value you are tightening to. Moving your hand closer to the socket reduces the total "foot-pounds" of torque you are applying, while moving it away, closer to the end of the wrench increases the "foot pounds of torque you are applying."
Crescent wrench The most common type of adjustable wrench found in most homes is the crescent wrench or a wrench with an adjustable end. These adjustable wrenches come in various sizes. A majority of homes have the normal 1 1/2" wrench that can be used to repair any type of faucet or pipe in the house. Large or small projects can be completed easily with the help of the crescent wrench. This angled jaw of the crescent wrench lies perpendicular to the handle at almost fifteen degrees. This tool finds a place in homes because of its ease of use. Most homes use this type of wrench to loosen any bolt or nut that may get stuck. Currently this type of adjustable wrench is used for undertaking other repair work also. Nowadays there are lid openers that incorporate the crescent wrench concept to make lid opening very easy. This type of wrench is also used to secure items such as doors when their faucets or handles have broken.
There are two basic types of torque wrenches on the market, what are called "beam" wrenches and "micrometer" wrenches. Beam wrenches count on the built-in flexibility of any material. As torque is applied, the wrench flexes, while another rod, with a pointer at the end, indicates torque being applied on a scale.
