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 special internal mechanisms.
GKN Ltd is a British multinational automotive and aerospace components business headquartered in Redditch, Worcestershire. It is a long-running business known for many decades as Guest, Keen and Nettlefolds. It can trace its origins back to 1759 and the birth of the Industrial Revolution.
Overdrive is the operation of an automobile cruising at sustained speed with reduced engine revolutions per minute (RPM), leading to better fuel consumption, lower noise, and lower wear. The term is ambiguous. The most fundamental meaning is that of an overall gear ratio between engine and wheels, such that the car is over-geared, and cannot reach its potential top speed, i.e. the car could travel faster if it were in a lower gear, with the engine turning at higher RPM.
Hardy Spicer is a brand of automotive transmission or driveline equipment best known for its mechanical constant velocity universal joint originally manufactured in Britain by Hardy employing patents belonging to US-based Spicer Manufacturing. Hardy and Spicer soon became partners. Later Spicer became Dana Holding Corporation.
A socket wrench is a type of spanner, 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.
Snap-on Incorporated is an American designer, manufacturer and marketer of high-end tools and equipment for professional use in the transportation industry including the automotive, heavy duty, equipment, marine, aviation, and railroad industries. Snap-on also distributes lower-end tools under the brand name Blue-Point. Their primary competitors include Matco, Mac Tools, Cornwell Tools, and Ko-Ken Tools.
A cheater bar, snipe, or cheater pipe is an improvised breaker bar made from a length of pipe and a wrench (spanner).
Nadcap is a global cooperative accreditation program for aerospace engineering, defense and related industries.
A lug nut or wheel nut is a fastener, specifically a nut, used to secure a wheel on a vehicle. Typically, lug nuts are found on automobiles, trucks (lorries), and other large vehicles using rubber tires.
A Hirth joint or Hirth coupling is a type of mechanical connection named after its developer Albert Hirth. It is used to connect two pieces of a shaft together and is characterized by tapered teeth that mesh together on the end faces of each half shaft.
SALTUS Industrial Technique GmbH, or SALTUS, located in Solingen/Germany is a part of the Swedish Atlas Copco Group with main office in Stockholm/Sweden. Saltus is integrated in the Group since 2013 as product company with focus of engineering and production of torque wrenches as well as sockets, bits and special, customized sockets.
The company of Warren and Brown was founded as a partnership in 1921 by Mr Andrew C. Brown and Mr William H. Warren, commencing at this time as “jobbing” engineers, specializing in tool making and gear cutting.
Multi-jackbolt tensioners (MJT) are an alternative to traditional bolted joints. Rather than needing to tighten one large bolt, MJTs use several smaller jackbolts to significantly reduce the torque required to attain a certain preload. MJTs range in thread sizes from 3⁄4 in (19 mm) to 32 in (810 mm) and can achieve 20 million pounds-force or more. MJTs only require hand-held tools, such as torque wrenches or air/electric impacts, for loading and unloading bolted joints.
A nut is a type of fastener with a threaded hole. Nuts are almost always used in conjunction with a mating bolt to fasten multiple parts together. The two partners are kept together by a combination of their threads' friction, a slight stretching of the bolt, and compression of the parts to be held together.
A torque multiplier is a tool used to provide a mechanical advantage in applying torque to turn bolts, nuts or other items designed to be actuated by application of torque, such as the actuation of valves, particularly where there are relatively high torque requirements.
Apex Tool Group is an American supplier of hand tools and power tools. It was formed as a joint venture of Cooper Industries and Danaher by the merger of Cooper Tools and Danaher's Tools and Components segment. In October 2012, Danaher and Cooper sold Apex to Bain Capital for about $1.6 billion. Apex is headquartered in Sparks, Maryland, and has over 20 factories globally including the United States, Canada, Mexico, Germany, China, and South America.
A hex key is a simple driver for bolts or screws that have heads with internal hexagonal recesses (sockets).
A battery torque wrench is a battery-operated torque wrench that can apply a specified torque without effort from the operator. It contains a planetary torque multiplier or a gearbox. A reaction device that absorbs the torque rather than the tool operator. The torque output is adjusted by varying the voltage on the motor. The battery torque wrench is used to remove stubborn nuts, or to apply accurate torque. The gearboxes can have multiplication ratios up to 125:1.
A centerlock wheel is a type of automobile wheel in which the wheel is fastened to the axle using a single, central nut, instead of the more common ring of 4 or 5 lug nuts or bolts.
