Stud Bolt is widely used for the flange connection.while flanges have various size and working classes according ASME B16.5.
Different size of the flanges would request different bolt size and length,so it is important for an engineer to know,how to calculate the stud bolt length.

The surface coating on a fastener is as important as the underlying fastener material. Fastener threads are manufactured in a cutting or forming machining process, and the surface coatings add an essential layer of protection to the fastener shank and threads
Choosing the right surface treatment for stud bolts depends on factors such as corrosion resistance, temperature, and environmental exposure. Below are the most common surface treatment options.(HDG,PTFE XYlan,ZINC Plating)
