Bolts are a type of fastener that consists of three parts: a head, a chamfer, and a shaft. A variety of bolts are used to position materials and objects. To secure the objects in place, a nut and a bolt are used. Bolts are sometimes referred to as screws because they have similar properties and distinguishing them is difficult. In layman's terms, a material is held together by a bolt, whereas screws fit directly.
Bolts are made of stainless steel because they require corrosion resistance from the elements. They are sometimes made from materials such as brass, zinc, and titanium. A variety of bolts are used in various applications, but the most common ones are anchor bolts, elevator bolts, carriage bolts, flanges, and others.
