Stainless steel stud bolts, or studs, are threaded fasteners with no specific head. They are tapered at both ends and utilized to connect two pieces, normally with nuts on both sides.
The absence of a head enables them to be employed where one component needs to be affixed on a permanent basis to another, the stud bolt itself functioning as an extended anchor. It's commonly utilized in industrial applications when there are flange connections involving pipes, valves, and pressure vessels.
Stainless steel is predominantly utilized, which is more resistant to heat and to corrosive materials. 304 and 316 grades are widely utilized to handle severe chemical environments, elevated temperatures, and elevated pressure.
Threads may be of varying lengths on each side, of which one would be normally short for close fit in a tapped hole. Stud bolts provide a solid and secure connection and are therefore an integral component of the oil and gas, petrochemical, and electric power generation sectors where reliability and safety are given.
