What is the characteristic of a stud bolt?

A stud bolt is characterized by having threads on both ends, which allows it to be secured into a nut on either side, providing more versatility for fastening two components together. This design is particularly advantageous for applications where the bolt needs to be removed or replaced without having to take the entire assembly apart. The double-threaded nature of stud bolts also facilitates a more secure and even distribution of mechanical loads, contributing to a reliable and robust connection in various piping systems.

The unthreaded characteristic mentioned in one of the choices does not apply to stud bolts, as they are specifically designed to be threaded for installation. Similarly, the options suggesting single-threading or temperature-specific properties do not accurately capture the defining feature of a stud bolt, which is the dual threading allowing for flexibility in assembly and maintenance.
