Bolts are a type of fastener generally used in conjunction with nuts for assembling two non-threaded components. The ease of use has made them suitable to play an essential role in developing mass production and steel structures. They consist of a head, and a cylindrical body externally threaded along part of their length.
ASTM A325 structural bolts are commonly made in one of two ways, cold forged or hot forged. Both methods result in a product that is similar in appearance but is made using a completely different process. The more common size structural bolts, readily available on the market, are mass-produced in large quantities using a cold forging method.
The industry uses thin fasteners to assemble products ranging from pipelines to heavy earthmoving equipment, cranes to bridges, and much more. Its primary function is to create a clamping force throughout the joint so that the joint can withstand operating conditions without loosening.
