Pliers Wrench
An adjustable spanner (UK and most other English-speaking countries) or adjustable wrench (US and Canada) is any of various styles of wrench, spanner (wrench) with a movable jaw, allowing it to be used with different sizes of fastener head (nut (hardware), nut, screw, bolt, etc.) rather than just one fastener size, as with a conventional fixed spanner. There are many forms of adjustable spanners; many of them are screw thread, screw-adjusted, whereas others use levers, and some early ones used wedges. Forms and names There are many forms of adjustable spanners; many of them are screw thread, screw-adjusted, whereas others use levers, and some early ones used wedges. The early taper-locking spanners needed a hammer to set the movable jaw to the size of the nut. The modern screw-adjusted spanner and lever types are easily and quickly adjusted. Some adjustable spanners automatically adjust to the size of the nut, using a motor and battery. Simpler models use a serrated edge to ...

Monkey Wrench
The monkey wrench is a type of adjustable wrench, a 19th century American refinement of 18th-century English coach wrenches. It was widely used in the 19th and early 20th century. It is of interest as an antique among tool collectors and is still occasionally used in maintenance and repair when it happens to be convenient. The term ''monkey wrench'' is also sometimes used loosely, usually by non-tradesman, to refer to the pipe wrench (owing to their broadly similar shapes). A wrench with smooth jaws is not used for turning threaded pipe. The largely US idiom "to throw a monkey wrench into..." means to sabotage something. The British English equivalent is "to throw a spanner in the works". The phrase "left handed monkey wrench" is sometimes used as ironic humor, as monkey wrenches are ambidextrously designed. Etymology and history The ''World English Dictionary'' gives a nautical definition for ''monkey'', as a modifier "denoting a small light structure or piece of equipme ...

Tongue-and-groove Pliers
Tongue-and-groove pliers are a type of slip-joint pliers. They are also known as: * adjustable pliers, * Channellocks ( i.e., Channellock brand pliers), * water pump pliers, * groove-joint pliers, * arc-joint pliers, * Multi-Grips, * tap or pipe spanners, * swan neck pliers. * Monkey pliers. Design They have serrated jaws generally set 45 to 60 degrees from the handles. The lower jaw can be moved to a number of positions by sliding along a tracking section under the upper jaw. An advantage of this design is that the pliers can adjust to a number of sizes without the distance in the handle growing wider. These pliers often have long handles—commonly 9.5 to 12 inches long—for increased leverage. The weight of the tool can also vary, depending on the material used. Uses Tongue-and-groove pliers are commonly used for turning and holding nuts and bolts, gripping irregularly shaped objects, and clamping materials. It is also possible to rotate objects while keeping them in ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Plumber Wrench
A plumber wrench (or plumber's wrench, pipe wrench, Swedish wrench or Swedish pattern wrench) is a form of plier described as a pipe wrench that uses compound leverage to grip and rotate plumbing pipes. Similar to the action of a Vise Grip plier, its jaw opening is adjusted to width by rotating a threaded ring. Its advantage is that it grips with significant force without needing to engage a lock nut like an adjustable tongue-and-groove plier. Like these, it can also be used on nuts, particularly hex shaped, and other flat engagement points. If used carelessly it can dent or break plumbing pipe. History The plumber wrench was invented in 1888 by the Swedish inventor named Johan Petter Johansson. It shares some principles with both the Stillson-pattern pipe wrench and the rigid pipe wrench, as well as various forms of adjustable pliers, such as the Vise Grip and "Channelock" tongue-and-groove plier. Johansson's tool is used rather than a pair of tongs to separate or join ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Pipe Wrench
A pipe wrench is any of several types of wrench that are designed to turn threaded pipe and pipe fittings for assembly (tightening) or disassembly (loosening). The Stillson wrench, or Stillson-pattern wrench, is the usual form of pipe wrench, especially in North America. The Stillson name is that of the original patent holder, who licensed the design to a number of manufacturers. The patent expired decades ago. Another type of wrench often used on pipes, the plumber wrench, is also called a pipe wrench in some places. The Stillson wrench is an adjustable wrench (spanner) with hardened serrated teeth on its jaws. The hard teeth bite into the softer metal of the round pipe and provide the grip needed to turn a pipe, even against fair resistance. The design of the adjustable jaw, which permits a certain amount of intentional play out of square, allows it to bind on the pipe, with forward pressure on the handle pulling the jaws tighter. On some models, two leaf springs, above and ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Locking Pliers
Locking pliers (also called Vise-Grips, a vice grip, Mole wrench or mole grips) are pliers that can be locked into position, using an "over-center" cam action. Locking pliers are available with many different jaw styles, such as needle-nose pliers, wrenches, clamps and various shapes to fix metal parts for welding. They also come in many sizes. History The first locking pliers, with the trade name Vise-Grip, were invented by William S. Petersen in De Witt, Nebraska, United States in 1924. Later, in 1955, in the United Kingdom, M K Mole and Son, a hand tool manufacturing company, under the managing direction of Thomas Coughtrie, began making nearly identical pliers. Etymology In the United States, the brand name "''Vise Grips''" is close to a generic name for this type of pliers. The same is true in the United Kingdom of the brand name "''Mole Wrench''". The spelling "''vise''" is mentioned in Samuel Johnson's 1755 dictionary. This spelling is orthodox in the United Stat ...

Knipex
Knipex (, mirroring German ) is a German manufacturer of pliers, pliers wrenches, and other tools, distributed for global sales. Its tools are principally for professional use in various trades, but they are also increasingly popular for DIY and EDC use as well. For four generations, Knipex has been an independent, owner-managed family company. Its headquarters are located in Wuppertal-Cronenberg. History The company was founded in 1882 by C. Gustav Putsch as a forge. In the early days manufacturing was focused on pincers and blacksmith’s tongs, initially handmade then increasingly produced using drop forging hammers and various machines. In 1942 Carl Putsch, the second generation representative, registered the “Knipex“ brand. Especially since the 1950s the program has constantly had additional types of pliers added to it. Karl Putsch took over as manager in 1954. Manufacturing operations became increasingly automated and product innovation took ever greater importance. ...

Chrome Vanadium
Chromium-vanadium steel (symbol Cr-V or CrV; 6000-series SAE steel grades, often marketed as "chrome vanadium") is a group of steel alloys incorporating carbon (0.50%), manganese (0.70-0.90%), silicon (0.30%), chromium (0.80-1.10%), and vanadium (0.18%). Some forms can be used as high-speed steel.Efunda (Retrieved September 30, 2012): Chromium and vanadium both make the steel more suitable for hardening. Chromium also helps resist abrasion, oxidation, and corrosion. Chromium and carbon can both improve elasticity.

Key (engineering)
In mechanical engineering, a key is a machine element used to connect a rotating machine element to a shaft. The key prevents relative rotation between the two parts and may enable torque transmission. For a key to function, the shaft and rotating machine element must have a keyway and a keyseat, which is a slot and pocket in which the key fits. The whole system is called a keyed joint. A keyed joint may allow relative axial movement between the parts. Commonly keyed components include gears, pulleys, couplings, and washers. Types There are five main types of keys: ''sunk'', ''saddle'', ''tangent'', ''round'', and ''spline''. Sunk key Types of sunk keys: ''rectangular'', ''square'', ''parallel sunk'', ''gib-head'', ''feather'', and ''Woodruff''. Parallel keys ''Parallel keys'' are the most widely used. They have a square or rectangular cross-section. Square keys are used for smaller shafts and rectangular faced keys are used for shaft diameters over or when the wall thickness o ...
