ASTM Specification for Bolt Fasteners
Check ASTM Nut Bolt Standard and Torque Chart
ASTM Bolts Grades includes various grades like B7, B16, B8, B8M and the material which is used is alloy steel, stainless steel, chromium-molybdenum and many more. Each and every grade has some unique properties and features, accordingly this is being manufactured. ASTM Nut Bolt Standard works on high pressure or high temperature environments. The have excellent finish and has excellent tolerance capacity. Usually used in flange connections and other industrial applications. ASTM stainless steel bolts has various specifications and dimensions as this is the one which is used in vessels, valves, flanges and fittings.
ASTM Stud Bolts
ASTM Fasteners
ASTM Nut Bolt Standard
ASTM standard for carbon steel bolts are high in ductility and can be easily welded. These are available in various forms like hex, square, round, threading and many other. Advanced techniques are used in order to manufacture this product. ASTM screw standard includes the specification like quenched and tempered alloy socket head cap screws. The screws need to be constructed with the help of steel and it also includes some of the chemical elements. ASTM washers are made up of carbon steel, weathering steel etc. This product is used with bolts, nuts, studs and other threaded fasteners.
Table of Content
ASTM Fasteners are generally used to mechanically join or fix the parts like nuts, bolts, screws of two pipes. This product includes the points like carbon steel shapes, plates, and bars of structural quality. This can be used in high temperature and works properly in high pressure environment. The corrosion resistance is good and thus ASTM Fasteners manufacturers are found in India on a large scale. Although there are numerous steel industries in Mumbai, but regal sales is the leading one. We are one of the prominent and trust-worthy steel firm in India, where all the products are manufactured using high-grade steel material. We are the ISO certified company and our name is well known in the steel industry.
