Stud
Industrial Studs, Threaded Studs and Double End Studs
AB Steel is an exporter, manufacturer and supplier of industrial studs in India, covering stainless steel studs, alloy steel threaded studs, carbon steel studs, duplex steel double end studs and nickel alloy studs. Each stud is produced to the diameter, length and thread specification required by the connection design, and supplied against the applicable material standard with the inspection documents requested at the order stage.
A stud is an externally threaded fastener used to make bolted connections in piping systems, pressure equipment and machinery. A single-end stud carries a threaded section at one end for a specific fastening arrangement, while a double-end stud is threaded at both ends so that one end can engage a tapped hole and the other can accept a nut. As a stainless steel studs manufacturer, we supply both configurations in standard and custom lengths.

FAQs
Stainless steel studs are used to create bolted connections in piping systems, industrial equipment, machinery and assemblies where corrosion resistance and reliable fastening are required.
A single-end stud has a threaded section at one end for a specific fastening arrangement. A double-end stud has threads at both ends, generally allowing one end to engage with a tapped hole and the other to accept a nut.
Depending on the application and availability, studs may be supplied in stainless steel, carbon steel, alloy steel, duplex stainless steel, super duplex stainless steel and nickel alloys.
The applicable standard depends on the material, application and connection design. ASTM A193 covers certain alloy and stainless steel bolting materials for pressure and temperature service, while thread dimensions must follow the specified thread standard.
Confirm the diameter, length, thread type, material grade, mechanical requirements, operating temperature, pressure conditions and corrosion exposure. The connection design and applicable engineering specification should guide final selection.
Provide the stud type, material grade, diameter, length, thread specification, quantity, applicable standard and any required inspection documents or material certificates.
