Clamping force is provided in between two pieces of material by the mechanical fasteners. There are wide varieties of fasteners available and are made of various types of materials. Materials used: The various materials used to make Detroit fasteners include steel, nickel, brass, and aluminum alloys. Nickel has the strength at high temperatures, which is its major advantage. The aluminum alloys have the properties of being lighter, more corrosion resistant and non magnetic. Among all these metals, steel is the most common material used. Factors for selection of a type of fastener: In addition to the type of material, there are various other factors for selection of a particular fastener. Life and service requirements, nature of the external loading on fastener, environmental, and also on the design of the components being joined are also the other factors. Fretting damage may be introduced by the use of Detroit fasteners like nuts and bolts for joints. At the area of contact of two metals, fretting, which is the wear process occurs, undergoing small cyclic slip. The fatigue strength is lowered by such damage, which is referred to as scuffing or galling. Power fasteners: These are the fasteners which are specially designed in order to improve the efficiency of them and also to withstand extreme conditions. Special material called hardened stainless steel is used to make these fasteners. Sometimes, with the use of an anti corrosive metal called titanium or zinc, the fastener is electroplated. These are used in construction work and in industries, where efficiency is not provided by the normal Detroit fasteners. Hammer drive and threaded stud are the two examples of fasteners. Normal ones can’t replace these power fasteners and so they shouldn’t be used where power fasteners are recommended. As they don’t get disintegrated due to heat, these are used in steel and iron industries. As titanium is much lighter and stronger than the steel, it is also regarded as power fasteners. These types don’t react with the blood and other parts if they are implanted in the body; they are also non corrosive and so they are used in surgeries. They are also used in airlines as they are durable and light weight. Wherever the normal ones are dangerous to use, the power ones are used. These are used in Grand prix race car wheels to increase its efficiency, performance and also to reduce weight of the car.
