WELDING STUD/ THREADED STUD

In manufacturing, a metal stud is a strong bolt used in the construction of buildings, motors, or manufacturing equipment. A threaded stud is a steal bolt that typically has threads on both sides. This bolt is screwed into a metal surface and placed between two objects. The object is secured with a nut on the adjacent threaded area of the bolt. Threaded studs are stronger then normal bolts because they are forged and cast into shape as a solid metal unit.

Threaded studs come in many sizes and materials.  These studs are used in all facets of construction and mechanical engineering. They are made of materials including stainless steel, aluminum, brass, and carbon steel.  Various types of studs are used for specific products, each of which require a particular material.
