    What is Screwdriver?

    Oppon 5-Point Repair Tool Screwdriver for iPhone 4

    • A screwdriver is a tool for driving screws and often containing rotating other machine elements with the mating drive system. The screwdriver is made up of a head or tip, which engages with a screw, a mechanism to apply torque by rotating the tip, and some way to position and support the screwdriver. A typical hand screwdriver comprises an approximately cylindrical handle of a size and shape to be held by a human hand, and an axial shaft fixed to the handle, the tip of which is shaped to fit a particular type of screw. The handle and shaft allow the screwdriver to be positioned and supported and, when rotated, to apply torque. Screwdrivers are made in a variety of shapes, and the tip can be rotated manually or by an electric motor or other motor.
    • A screw has a head with a contour such that an appropriate screwdriver tip can be engaged in it in such a way that the application of sufficient torque to the screwdriver will cause the screw to rotate.

    History:

    • The earliest screwdrivers of which written evidence remains were used in Europe in the late Middle Ages. It seems that they were probably invented in either Germany or France, in the late 15th century. The tool's original names in German and French were Schraubendreher (screwturner) and tournevis (turnscrew), respectively, reflecting the native linguistic patterns of Germanic and Romance languages ("noun-verber" and "verb-noun", respectively). The first documentation of the tool is in The Medieval Housebook of Wolfegg Castle, a manuscript written sometime between 1475 and 1490.[1] These earliest screwdrivers had pear-shaped handles and were made for slotted screws (diversification of the many types of screwdrivers did not emerge until the Gilded Age). The screwdriver remained inconspicuous, however, as evidence of its existence throughout the next 300 years was based primarily on the presence of screws.
    • Screws were used in the 15th century for constructing screw-cutting lathes, securing breastplates, backplates, and helmets on medieval jousting armor, and eventually for multiple parts of the emerging firearms, particularly the matchlock. Screws, hence screwdrivers, were not used in full combat armor, most likely to give the wearer freedom of movement.
    • The jaws holding the pyrites inside medieval guns were secured with screws, and the need to constantly replace the pyrites resulted in considerable refinement of the screwdriver. The tool was much more documented in France, and took on many different shapes and sizes, though every version was still for slotted screws. There were large, heavy duty screwdrivers for building and repairing large machines, and smaller screwdrivers for refined cabinet work.
    • Illustration from Robertson's patent applicationThe screwdriver was entirely dependent on the screw, and it was not until several advances that the screw became easy enough to produce to become popular and widespread. The most popular door hinge at the time was the butt-hinge, but it was considered a luxury. The butt-hinge was handmade, and its constant motion meant that it required the security of a screw.
    • Screws were very hard to produce before the First Industrial Revolution, requiring manufacture of a conical helix. The brothers Job and William Wyatt found a way to produce a screw on an assembly line machine that first cut the slotted head, and then carved the helix. Though their business ultimately failed, their contribution to the screw ultimately led to a vast increase in the screw and the screwdriver's popularity.
    • The increase in popularity ultimately lead to refinement and eventually diversification of the screwdriver. Refinement of the precision of screws also significantly contributed to the boom in production, mostly by increasing its efficiency and standardizing sizes, important precursors to industrial manufacture.
    • Close-up of Robertson screwCanadian P.L. Robertson, although he was not the first person to patent the idea of socket-head screws, was the first person to successfully commercialize them, starting in 1908. Socket screws rapidly grew in popularity, and are still a favorite of mechanics today for their resistance to wear and tear, compatibility with hex keys, and ability to stop a power tool when set. Though immensely popular, Robertson had trouble marketing his invention to the newly booming auto industry, for he was unwilling to relinquish his patents.
    • Meanwhile, Henry F. Phillips patented his own invention, an improved version of a deep socket with a cruciform, today known as the Phillips Screw. The Phillips screw was offered by Phillips to the American Screw Company, and after a successful trial on the 1936 Cadillac, quickly swept through the American auto industry. With the Industrial Revival at the end of the Great Depression and the onslaught of World War II, the Phillips screw quickly became, and still remains, the most popular screw in the world. A main attraction for the screw was that conventional slotted screwdrivers could also be used on them, which ostracized the Robertson Screw, still a favorite among experts.
    • Phillips screw headThe screwdriver remains one of the most common tools both in household use and in professional manufacture.
    • Gunsmiths still refer to a screwdriver as a "turnscrew", under which name it is an important part of a set of pistols. The name was common in earlier centuries, used by cabinet makers and shipwrights and perhaps other trades.
    • The Cabinet-Maker's screwdriver is one of the longest-established handle forms, somewhat oval or ellipsoid in cross section. This is variously attributed to improving grip or preventing the tool rolling off the bench. The shape has been popular for a couple of hundred years. It is usually associated with a plain head for slotted screws, but has been used with many head forms. Modern plastic screwdrivers use a handle with a roughly hexagonal cross section to achieve these same two goals, a far cry from the pear-shaped handle of the original 15th century screwdriver.
