General introduction

high strength stud is a stub whose strength is high. In manufacturing, a metal stud is a strong bolt used in the construction of buildings, motors, or manufacturing equipment. Typically a high strength stud is a bolt that has threads on both sides. This stub 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. Studs are stronger then normal bolts because they are forged and cast into shape as a solid metal unit. A normal threaded bolt has a single threaded side with a nut head on the opposite side, which used for tightening. This design is weaker than a high strengthen stud because the nut head can break off under tension. A high strengthen nut and bolt design will not break under tension because the nut is screwed onto the stud.

High strength studs can be found in automobiles. Most motors include heads, which are placed on the top of the motor. High-performance cars use a high strength stud to provide additional strength for the head attachment. The studs are screwed into the motor and the head is then placed on the studs, where it is tightened to the motor with a nut on the apposing threaded area of the stud. This provides better strength than single-steel threaded bolt designs. High strength 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, nylon, and carbon steel. Various types of studs are used for specific products, each of which requires a particular material.
