A threaded rod, also known as a stud or all-thread, is a type of fastener that consists of a long, cylindrical rod with threads along its entire length. Threaded rods are typically made of steel or other metals and are used to create a strong and secure connection between two components by threading into pre-tapped holes or nuts.

Threaded rods come in various lengths, diameters, and thread pitches to suit different applications, and can be customized with different types of ends, such as threaded, plain, or chamfered. They are commonly used in construction, electrical installations, plumbing, and other industries where a secure and adjustable connection is needed.
