316 Stainless Steel Studs and ASTM A193 Grade B8 Partially Threaded Stud exporter & supplier in India

Stud Bolt is also known as bolting material or fastener. Bolting is the term that used to tighten the flange joints connection. The tightening of the flange ensures the leak-proof connection between the flange and gasket. Stainless Steel Studs has good machinability and it can be readily fabricated. It is usually mechanically fastened with screws. Stainless Steel Stud Bolts has a thread on full-lengths or at both ends. It consist three elements if washers are not used. SS 304 Stud Bolt is externally threaded fasteners without a head, used with 2 nuts on either side, substituting a usual "bolt & nut" assembly. It is most notably present in kitchen equipment and industrial applications. It provides good corrosion resistance to many chemical corrodents, as well as industrial atmospheres and it is highly heat-resistant. With good formability, it can be readily welded by all common methods. 316 Stainless Steel Stud Bolts are prominently used in flange connections. Depending upon their design and threading patterns. It has better corrosion and pitting resistance to chlorides and higher levels of strength at elevated temperatures. This is it ideal for applications as pumps, valves, textile and chemical equipment, pulp & paper and marine applications. Partially Threaded Studs are used in all types of applications. It can be welded to a flat surface, or to the inside or outside of an angle. Fully Threaded Studs have no head and are threaded along their entire length, and provides a higher tensile strength. It is ideal for making custom assemblies using thread-locking adhesive – including stud-type hand knobs and cushion spindles for Toggle Clamps.
