The power grid in the United States is complex, made up of generating stations, substations, transmission lines, as well as step-up and step-down transformers. Each of these is designed by the utility industry to fit within the larger power system, with the goal of moving power safely with as little loss over the greatest distance to the most people as possible. No easy task. For example, consider just one part of the system: latticed transmission
Choosing the Best Bolt According to Frederick E. Graves of The Scientific American, a refrigerator has 275 bolts, a fork-lift has 940, a car has 3,500, and a jet plane has 1.5 million. Essentially, the world is held together with bolts. But what is a bolt? Graves says it’s a “cylindrical, externally threaded fastener with a head.” Unlike a screw, though, a bolt is meant to be used with a nut rather than in tapped
Bolt and Screw Heads Anyone who is familiar with fasteners can tell you that there are almost unlimited options available. For each fastener type, there are many different shapes, sizes and materials that can be customized based on your unique needs. So, in this blog post, we’ll take a look at some of the most common types of bolt and screw heads and their uses. Common Types Pan Heads These are one of the most
Common Types of Washers Washers are typically used to help distribute the shock load of threaded fasteners. This prevents them from becoming damaged or unscrewed during normal operations. Washers are thin, usually disk-shaped plates with holes in the middle for workers to install fasteners through. They’re generally made of metal or plastic materials. In this blog post, we’ll take a look at three of the most common types of washers and some examples of each.
Common Types of Corrosion There are many types of corrosion that can degrade a metal. But first – what exactly is corrosion? Corrosion happens when a metal’s inherent properties start to degrade. It’s defined as the deterioration of a metal due to chemical reactions between it and the surrounding environment. The rate of deterioration is determined by the type of metal and the environmental conditions it’s in. All metals can corrode. However, some metals deteriorate
