 AUTOMOTIVE NUT                                                  Source:Ram-Bull omotive Nuts A nut is a type of fastener with a threaded hole . Nuts are almost always used opposite a mating bolt to fasten a stack of parts together. The two partners are kept together by a combination of their threads' friction, a slight stretch of the bolt, and compression of the parts. In applications where vibration or rotation may work a nut loose, various locking mechanisms may be employed. Automotive nuts, one of the important types of auto fasteners are usually square or hexagonal shaped metal having a threaded hole which is used for screwing a bolt that hold together temporary or permanent structures through which bolt passes.

  FASTENERS Fasteners Source:Rainbowelectronics.com      An automobile vehicle is an assembly of a large number of sub-assemblies and components. The assemblies such as engine-clutch-gearbox-differential-wheels-brakes etc. together may form a vehicle. Each of these assemblies is formed by joining many components. Some of the components or sub-assemblies can move with respect to each other, others are physically fixed together, with no relative motion possible. The first type of connection is called a kinematic joint, and the second type is called a rigid joint (or a structure). Both types of joints are important in manufacturing a vehicle, and there are many ways of achieving such joints. The process and methods used for joining depend on the type of joint, the required strength, the materials of the components being joined, the geometry of the components, and cost issues. There are five most common methods of joining:           ...
