        rack is a standardized frame or enclosure for mounting multiple equipment modules. Each module has a front panel that is 19 inches (482.6 mm) wide, including edges or ears that protrude on each side which allow the module to be fastened to the rack frame with screws. Equipment designed to be placed in a rack is typically described as rack-mount, rack-mount instrument, a rack mounted system, arack mount chassis, subrack, rack mountable, or occasionally simply shelf. The height of the electronic modules is also standardized as multiples of 1.752 inches (44.50 mm) or one rack unit or U (less commonly RU)The industry standard rack cabinet is 42U tall. The term relay rack appeared first in the world of telephony.[2] By 1911, the term was also being used in railroad signaling There is little evidence that the dimensions of these early racks were standardized. The 19-inch rack format with rack-units of 1.75 inches and holes tapped for 12-24 screws with alternating spacings of 1.25 inches and 0.5 inch was an established standard by 1934. A screw, or bolt, is a type of fastener, typically made of metal, and characterized by a helical ridge, known as a male thread(external thread) or just thread, wrapped around a cylinder. Some screw threads are designed to mate with a complementary thread, known as a female thread (internal thread), often in the form of a nut or an object that has the internal thread formed into it. Other screw threads are designed to cut a helical groove in a softer material as the screw is inserted. The most common uses of screws are to hold objects together and to position objects.
