An adjustable spanner (UK and most other English-speaking countries), also called a shifting spanner (Australia and New Zealand) [1] or adjustable wrench (US and Canada), [a] is any of various styles of spanner (wrench) with a movable jaw, allowing it to be used with different sizes of fastener head (nut, bolt, etc.) rather than just one fastener size, as with a conventional fixed spanner.
In South Africa, the terms "bobbejaan spanner" and "baboon spanner" are commonly used, [6] especially for large pipe wrenches. Bobbejaan is the Afrikaans term for a baboon. In Spain and Morocco, they are called grifa. In Mexico they are known and called "stillson" without even using the word llave ("wrench"). In Turkey they are known as ...
A click torque wrench. A torque wrench is a tool used to apply a specific torque to a fastener such as a nut, bolt, or lag screw.It is usually in the form of a socket wrench with an indicating scale, or an internal mechanism which will indicate (as by 'clicking', a specific movement of the tool handle in relation to the tool head) when a specified (adjustable) torque value has been reached ...
Socket set with ratchet (above), four hex sockets and a universal joint. A socket wrench (or socket spanner) is a type of spanner (or wrench [1] in North American English) that uses a closed socket format, rather than a typical open wrench/spanner to turn a fastener, typically in the form of a nut or bolt.
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.g. tap wrench and pipe wrench), or may be used for a monkey wrench—an adjustable pipe wrench. [1] In North American English, wrench is the standard term.
A breaker bar is able to create a larger amount of rotational force compared to a standard socket wrench. A standard breaker bar is strong enough to allow the user to apply up to 2,500 pound-feet (3,400 N⋅m) of torque without breaking the bar. [3] A high-end 1/2" socket wrench can withstand a maximum of 500 pound-feet (680 N⋅m) of torque. [4]
They were set either by sliding a wedge, or later by twisting the handle, which turned a screw, narrowing or widening the jaws. In 1840, Loring Coes , a knife manufacturer in Worcester , Massachusetts, invented a screw-based coach wrench design in which the jaw width was set with a spinning ring fixed under the sliding lower jaw, above the handle.
The cheater bar itself can become part of a de facto catapult with the worker in the line-of-fire. [1] If the over-torqueing results in the failure of any of the items in the jury rig, the fragments can injure workers in the line-of-fire. [2] The use of the cheater bar can result in component damage that can, in turn, harm workers. [3]
