What is the difference between a bolt and a stud? A bolt is defined as a headed fastener with a threaded shaft. On the other hand, a stud is a type of fastener that does not have a head, a shaft that is threaded on both ends and may or may not be threaded in the middle section.
Both bolts and studs are required to comply with the ASTM or American Society for Testing and Materials specifications. Examples of ASTM-compliant products include A193 B7 bolts and A193 B7 studs. Bolts and studs can be made of super duplex stainless steel, brass and different types of metals.
Given their similarities, it is not unusual that some used these terms interchangeably. Besides, these materials basically serve the same functions. They both fasten two separate objects together by using a nut or nuts. However, it is this difference in their structure that determines how and when each should be used.
One significant difference between the two is how bolts and studs react to strain - specifically tensile strain. Because it fastens with two nuts, a stud will not experience a twisting force, only a pulling force. A bolt will be both subjected to a twisting force around its head and a pulling force along its body. This makes studs more ideal for use to conditions where it will be subjected to a lot of movement, such as in automotive works.
Bolts, on the other hand, cost relatively cheaper than studs. This is because they are easier to mass produce. This makes bolts a more practical option for routine fastening needs. This also means bolts are easier to find as any online nuts and bolts supplier or super duplex bolt suppliers would have a variety of bolts on stock.
But of course studs are needed just as much as bolts. So don't think you'll find it hard looking for this kind of fastener. If what you need are more studs for your fastening needs, don't panic. You can look for these materials in a specialty supplier. Nowadays, there are a few specialty supplier of nuts and bolts that sell their products online.
