A wrench or spanner is a tool used to provide grip and mechanical advantage in applying torque to turn objects—usually rotary fasteners, such as nuts and bolts—or keep them from turning.

In Commonwealth English excluding Canada , spanner is the standard term. The most common shapes are called open-ended spanner and ring spanner. The term wrench is generally used for tools that turn non-fastening devices e. 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.

Higher quality wrenches are typically made from chromium-vanadium alloy tool steels and are often drop-forged. They are frequently chrome-plated to resist corrosion and for ease of cleaning. Hinged tools, such as pliers or tongs, are not generally considered wrenches in English, but exceptions are the plumber wrench pipe wrench in British English and Mole wrench sometimes Mole grips in British English.

The word can also be used in slang to describe an unexpected obstacle, for example, 'He threw a spanner into our plans' in U. English, 'monkey wrench'.

Contents1 History2 Types3 Other types of keys4 Size designations5 See also6 References7 External linksHistory[edit]Wrenches and applications using wrenches or devices that needed wrenches, such as pipe clamps and suits of armor, have been noted by historians as far back as the 15th century. The mid 19th century began to see patented wrenches which used a screw for narrowing and widening the jaws, including patented monkey wrenches.

Most box end wrenches are sold as 12 point because 12 points wrenches fit over both 12 point and 6 point bolts. However, 12 point wrenches have been known to round off 6 point bolts as they provide less contact space. This wrench is often double-ended, with a different-sized opening at each end.

The ends are generally oriented at an angle of around 15 degrees to the longitudinal axis of the handle. This allows a greater range of movement in enclosed spaces by flipping the wrench over. 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. Both ends generally fit the same size of bolt. 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. Ratcheting can be reversed by flipping over the wrench, or by activating a reversing lever on the wrench.

This type of wrench combines compact design of a box wrench, with the utility and quickness of use of a ratchet wrench. A variety of ratcheting mechanisms are used, from simple pawls to more complex captured rollers, with the latter being more compact, smoother, but also more expensive to manufacture.

The one pictured also features a drift pin on the tail. A Saltus wrench features a socket permanently affixed to a handle. Sockets are not interchangeable as with a socket wrench. The socket often rotates around the handle to allow the user to access a fastener from a variety of angles.

Commonly a Saltus wrench is part of a double-ended wrench, with an open-end type head on the opposite side from the socket head. Note the difference in the American and British senses of the word 'spanner'.

In American English, 'spanners' are a subset of the class of tools called 'wrenches'. Used commonly with large fasteners, especially a nut and stud which both have index marks: the nut is screwed hand-tight, then further tightened with the striking wrench a known number of index marks calculated from the elasticity of the bolt or stud, thus giving precise torque preload.

The adjustable end wrench differs from the monkey wrench in that the gripping faces of the jaws are displaced to a typically 15 degree angle relative to the tool's handle, a design feature that facilitates the wrench's use in close quarters.

The modern adjustable end wrench was invented by Johan Petter Johansson [4]of Bahco. The common use of 'Crescent wrench' to describe this design is derived from the Crescent brand, owned by Apex Brands, Inc. Sometimes known by the original patent holder's brand name as a 'Stillson wrench'. It may include a handle, if it does not then it is often just referred to as a socket and is usually used with various drive tools to make it a wrench or spanner such as a ratchet handle, a tee bar sliding tommy bar bar or a knuckle bar single axis pivot.

It generally has a six-point, eight-point or twelve-point recess, may be shallow or deep, and may have a built-in universal joint. The photo shows both ratchet and sockets. 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. 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.

The socket-driving analog of the brace used to drive a drill bit. Used instead of a ratchet in a few contexts when it can save substantial time and effort—that is, when there is a lot of turning to be done many fasteners , ample room to swing the handle, ample access to the fastener heads, etc.

Has less leverage than a conventional ratchet wrench. Used occasionally in automotive repair or job shop work. 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. Another wrench designed for internal socket-head screws and bolts.

The cross-section resembles a square-toothed gear. Not a common design, it is chiefly used on small set screws. The cross-section resembles a star. Commonly used in automobiles, automated equipment, and computer components as it is resistant to wrench cam-out and so suitable for use in the types of powered tools used in production-line assembly. A formerly common type of wrench that was popular with mechanics, factory workers, and farmers for maintenance, repair and operations tasks in the days when fasteners often had square rather than hex heads.

The wrench's shape suggests the open mouth of an alligator. 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.

This key is often interchangeable with radiator bleed keys. It is turned with a short length of rod tommy bar or T bar inserted through two holes in the middle of the tube. A tool commonly used to open bungs on large gallon drums cylindrical containers. The hose connection has a threaded collar with a protruding pin.

From the handle of the wrench an arc has at its end a loop to engage the pin. This is a pentagonal five-sided box wrench. The unusual shape of the lug makes the valve tamper-resistant: with the opposite faces nonparallel, unauthorized opening of the hydrant is more difficult without a suitable tool. The valve usually has a rectangular lug and is set deep into the ground, requiring the key.

A T-handle wrench with two pins and clearance for the spike—allows removal and insertion of spikes in shoes. A flat wrench with a circular hole and two inward protruding pins to engage slots in the nut. This type of nut is used on bicycles to secure the front fork pivot bearing to the headpiece of the frame. It may be either a strap-type wrench or a socket.

Used to tighten or loosen fasteners located in recesses. The handle is offset to make the wrench more convenient to grip, and the handle is short to fit between spokes, allowing the wrench to turn degrees without being removed. Similar to a strap wrench, but uses positive engagement rather than friction, and so needs to grab only one end of the chain.

It relies entirely on friction between the strap or chain and the object to be manipulated. Similar to a pipe wrench, but uses a chain similar to a drive chain or strap, instead of an adjustable jaw. The links of the chain have extended pegs which fit into grooves in the front of the handle, with one end of the chain attached permanently to the handle. This is used in situations where pipe wrenches cannot maintain a proper grip on an object such as a wet or oily pipe.

Larger versions of chain wrenches are sometimes known as 'bull tongs' and are used with large diameter pipe such as is used deep wells. 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.

Similar, and in some cases identical to drum tuning keys, but often provide greater torque due to the higher tension of strings. It is generally advised[by whom? It is a 'hand saver' more than anything else. An adjustable wrench with a small number usually 2—4 of discrete sizes. This is sometimes used as an inexpensive substitute for a monkey wrench.

A broad type of wrenches that use electricity or compressed air to power the wrench.
