Nutdrivers
A nutdriver or nut driver is a hand tool for tightening or loosening nuts and bolts. It essentially consists of a socket attached to a shaft and cylindrical handle and is similar in appearance and use to a screwdriver. They generally have a hollow shaft to accommodate a shank onto which a nut is threaded. They are typically used for lower torque applications than wrenches or ratchets and are frequently used in the appliance repair and electronics industries. Variations include T-shaped handles for providing the operator with a better grip, ratcheting handles, sockets with recessed magnets for holding fasteners, and flex shafts for bending around obstructions. Indexable bits with the same purpose, to be held either in indexable handles or in power tool chucks, are called nutsetters. A spinner handle is a shaft and handle with a drive fitting—most commonly square axle at the end for attaching interchangeable sockets. This allows one to use a single handle with a number of s ...

Xcelite
Xcelite is a brand of hand tools geared towards the electronics service industry. It is currently owned by Apex Tool Group and markets screwdrivers, nut drivers, pliers, and various specialized electronics tools. History Xcelite was founded in 1921 by F. Birney Farrington (1886-1962), as the Park Metalware Company, Inc., a small metalworking shop in Orchard Park, New York. John Zilliox’s (1874-1971) for an adjustable wrench, launched the company into manufacturing hand tools for worldwide distribution. The company marketed tools under the "XCEL" and, later, "Xcelite" brand names. John N. Petre (1891-1952) held six patents assigned to Park Metalware. Among his important inventions was the interchangeable shaft screwdriver . By 1952, the Xcelite brand name was so well known in the electronics, television and radio repair industries, the company changed its corporate name to Xcelite, Inc.

Easco
Easco Hand Tools was an American manufacturer of hand tools. It is best known for being the main supplier of mechanic's tools for the Craftsman brand. Its tools were also sold under the Allen and ''KD Tools'' brands after its acquisition by Danaher Corporation. The brand name was gradually phased out by Danaher. History The company began as ''Moore Drop Forging Company'' in Springfield, Massachusetts in 1900 or 1901. In 1938 Moore became a vendor for Sears Roebuck. In 1967, Moore Drop Forging was acquired by ''Eastern Stainless Steel Corporation'' (Easco), a manufacturer of stainless and specialty steel. Easco continued the Craftsman contract with Sears. By 1969, the parent company was known as Easco Corporation. Tools made by MDF for Sears have a "V" maker's mark on them, those by Danaher had a "V^" (V and upside down V, sometimes a right-side up V). Variations of the "VV" exist including three digit codes on tools such as ratchets. It is believed that these denote the tim ...

Socket Wrench
A socket wrench (or socket spanner) is a type of spanner (or wrench 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 prevalent form is the ratcheting socket wrench, often informally called a ratchet. A ratchet incorporates a reversible ratcheting mechanism which allows the user to pivot the tool back and forth to turn its socket instead of removing and repositioning a wrench to do so. Other common methods of driving sockets include pneumatic impact wrenches, hydraulic torque wrenches, torque multipliers and breaker bars. Some lesser known hybrid drivers include striking wrench tools with square drive, and hydraulic impact wrenches (typically powered by on site hydraulic power such as present with military tanks, and many rail car applications). Interchangeable sockets The basic contemporary form of socket is hexagonal, referred to as "6-point" for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hand Tool
A hand tool is any tool that is powered manual labour, by hand rather than a motor. Categories of hand tools include wrenches, pliers, cutter (other), cutters, File (tool), files, hammer, striking tools, chisel, struck or hammered tools, screwdriver, screwdrivers, vises, clamp (tool), clamps, snips, hacksaws, drills, and knives. Outdoor tools such as garden forks, pruning shears, and Rake (tool), rakes are additional forms of hand tools. Portable power tools are not hand tools. History Hand tools have been used by humans since the Stone Age, when stone tools were used for hammering and cutting. During the Bronze Age, tools were made by casting alloys of copper and tin. Bronze tools were sharper and harder than those made of stone. During the Iron Age iron replaced bronze, and tools became even stronger and more durable. The Ancient Rome, Romans developed tools during this period which are similar to those being produced today. After the Industrial Revolution, most tools ...

Nut (hardware)
A nut is a type of fastener with a screw thread, threaded hole. Nuts are almost always used in conjunction with a mating bolt (fastener), bolt to fasten multiple parts together. The two partners are kept together by a combination of their threads' friction with slight deformation (engineering)#Elastic deformation, elastic deformation, a slight Tension (physics), stretching of the bolt, and compression (physics), compression of the parts to be held together. In applications where vibration or rotation may work a nut loose, various locking mechanisms may be employed: lock washers, jam nuts, eccentric double nuts, specialist adhesive thread-locking fluid such as Loctite, safety pins (split pins) or lockwire in conjunction with castellated nuts, nylon inserts (nyloc nut), or slightly oval-shaped threads. Square nuts, as well as bolt heads, were the first shape made and used to be the most common largely because they were much easier to manufacture, especially by hand. While rare toda ...

Screw
A screw is an externally helical threaded fastener capable of being tightened or released by a twisting force (torque) to the screw head, head. The most common uses of screws are to hold objects together and there are many forms for a variety of materials. Screws might be inserted into holes in assembled parts or a screw may form its own thread. The #Differentiation between bolt and screw, difference between a screw and a bolt is that the latter is designed to be tightened or released by torquing a Nut (hardware), nut. The screw head on one end has a slot or other feature that commonly requires a tool to transfer the twisting force. Common tools for driving screws include screwdrivers, wrenches, coins and hex keys. The head is usually larger than the body, which provides a ''bearing surface'' and keeps the screw from being driven deeper than its length; an exception being the ''set screw'' (aka grub screw). The cylindrical portion of the screw from the underside of the head t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Screwdriver
A screwdriver is a tool, manual or powered, used for turning screws. Description A typical simple screwdriver has a handle and a shaft, ending in a tip the user puts into the screw head before turning the handle. This form of the screwdriver has been replaced in many workplaces and homes with a more modern and versatile tool, a power drill, as they are quicker, easier, and can also drill holes. The shaft is usually made of tough steel to resist bending or twisting. The tip may be hardened to resist wear, treated with a dark tip coating for improved visual contrast between tip and screw—or ridged or treated for additional "grip". Handles are typically wood, metal, or plastic and usually hexagonal, square, or oval in cross-section to improve grip and prevent the tool from rolling when set down. Some manual screwdrivers have interchangeable tips that fit into a socket on the end of the shaft and are held in mechanically or magnetically. These often have a hollow handle that ...

Torque
In physics and mechanics, torque is the rotational analogue of linear force. It is also referred to as the moment of force (also abbreviated to moment). The symbol for torque is typically \boldsymbol\tau, the lowercase Greek letter ''tau''. When being referred to as moment of force, it is commonly denoted by . Just as a linear force is a push or a pull applied to a body, a torque can be thought of as a twist applied to an object with respect to a chosen point; for example, driving a screw uses torque to force it into an object, which is applied by the screwdriver rotating around its axis to the drives on the head. Historical terminology The term ''torque'' (from Latin , 'to twist') is said to have been suggested by James Thomson and appeared in print in April, 1884. Usage is attested the same year by Silvanus P. Thompson in the first edition of ''Dynamo-Electric Machinery''. Thompson describes his usage of the term as follows: Today, torque is referred to using d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wrench
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 the UK, Ireland, Australia, and New Zealand ''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.g. tap wrench and pipe wrench), or may be used for a monkey wrench—an adjustable pipe wrench. In North American English, ''wrench'' is the standard term. The most common shapes are called ''open-end wrench'' and ''box-end wrench''. In American English, ''spanner'' refers to a specialized 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electronics
Electronics is a scientific and engineering discipline that studies and applies the principles of physics to design, create, and operate devices that manipulate electrons and other Electric charge, electrically charged particles. It is a subfield of physics and electrical engineering which uses Passivity (engineering), active devices such as transistors, diodes, and integrated circuits to control and amplify the flow of electric current and to convert it from one form to another, such as from alternating current (AC) to direct current (DC) or from analog signal, analog signals to digital signal, digital signals. Electronic devices have significantly influenced the development of many aspects of modern society, such as telecommunications, entertainment, education, health care, industry, and security. The main driving force behind the advancement of electronics is the semiconductor industry, which continually produces ever-more sophisticated electronic devices and circuits in respo ...

Ratchet (device)
A ratchet (occasionally spelled rachet) is a mechanical device that allows continuous linear or rotary motion in only one direction while preventing motion in the opposite direction. Ratchets are widely used in machinery and tools. The word ''ratchet'' is also used informally to refer to a ratcheting socket wrench. __TOC__ Theory of operation A ratchet consists of a round gear or a linear rack with teeth, and a pivoting, spring-loaded finger called a '' pawl'' (or ''click'', in clocks and watches) that engages the teeth. The teeth are uniform but are usually asymmetrical, with each tooth having a moderate slope on one edge and a much steeper slope on the other edge. When the teeth are moving in the unrestricted (i.e. forward) direction, the pawl easily slides up and over the gently sloped edges of the teeth, with a spring forcing it (often with an audible 'click') into the depression between the teeth as it passes the tip of each tooth. When the teeth move in the oppo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
