A stud is a special type of fastener used to strengthen the connection of materials. It has two heads that can be used in the coils on both sides, which can better fix the distance between the two coils. Studs are commonly used for structural connections of large structures such as buildings, bridges and aircraft. In addition, double-ended studs are also a commonly used fastener in shipbuilding technology, which can usually reduce the pressure between nuts and studs and prolong the service life of the structure. The advantages of double-ended studs include high strength, corrosion resistance, customized size according to customer requirements, and high temperature and high pressure resistance.
Double end studs are fasteners that have threads on both ends, allowing them to be screwed into two separate components.
