union spring fastener studs are a type of fastener used in sheet metal, thin plates, chassis, and cabinets. During connection, one end must be screwed into a part with an internal threaded hole, while the other end passes through a part with a through-hole, and then a nut is tightened, firmly connecting the two parts into a single unit. This type of connection is called a stud connection and is a detachable connection, primarily used when one of the connected parts has a large thickness, requires a compact structure, or involves frequent disassembly where bolted connections are not suitable. The press-fit nut stud has a hexagonal shape at one end.
