Detailed Information

Prashaant Steel & Alloys is a leading producer of Stud Bolt and a high-calibre retailer. Thanks to their excellent resistivity properties, the Stud Bolt that we manufacture are extremely popular in the industry. We are considered to have the excellent quality of Tap End Studs at Prashaant Steel & Alloys, which is why we use the highest quality of the raw materials used in the production processes. The Stud Bolt provides outstanding resistance to corrosion and oxidation, which opens its doors to a wide range of applications. 

Stainless steel stud bolts are usually used in pressure vessels, industrial boilers, condensers and pipelines. This has two heavy hexagon nuts and has one head with one nut. To increase the corrosion resistance of this product, some coatings like xylan, Teflon and other such are done. It is a type of fastener that connects a nut or washer and other parts of it. BS 4882 stud bolts have specifications like diameter, length, material, class and many other things. The dimension chart of this consists of various sections such as diameter, diameter size maximum and minimum and lot more.

Welding means attaching a fastener to another metal and Welded stud bolts are the one which is used in cylinder head applications, and many other industrial areas. The specification includes various materials and the sizes of it. These are used in various other shapes, sizes and types. ASTM standards for stud bolts are made of materials like carbon, alloy, and stainless steel. These are used in high pressure and high temperatures.

Carbon steel stud bolts contain thread rods of 60000 tensile strength in sizes from ¼ inch to 4 inches in diameter. Using an A36 round bar, this product is manufactured. This product can sustain high temperatures and high pressures. Chrome moly stud bolts are usually used in industrial areas like petrochemical, oil and gas industry and also in many other sectors. 

Bolt is similar to screw and it is a form of thread fastener and stud bolts manufacturers are developed in India. Although there are many such steel companies in India, the one which is leading and well-known is Prashaant Steel & Alloys. We use superior material to manufacture this product. Even our team is highly qualified to manufacture this product. Our timely delivery is the reason because of which our name is still at the top position in the market.
