ASTM A563 is a specification that covers alloy steel and carbon steel nuts from various material grades that range from ¼ inches to 4 inches in size. Suraj Metal Corporation is a leading manufacturer and supplier of the different types such as the Hex Jam Nut and others. There are different types, threads and lengths of these nuts.
These can be nuts for fittings, flanges or general purpose applications. Depending on the application types the nut types vary as hex flange nut and fitting nuts. There are different grades such as A, B, C, C3 and so on. These differentiate between the different chemical and mechanical properties of the products. They are also available in different specifications such as the din 934 Hex nut and are used in different application types. The different grades are made up of different materials and production methods such as carbon steel, quenched and tempered, weathering steel, etc. The hex coupling nut is used to make a connection between two tubular components to make a coupling. These nuts come in different sizes such as the m6 hex nut and are used in different applications ranging from weathering, corrosive and general corrosive services. The nuts can sometimes be exceptionally longer than usual and these Long Hex Nut types are used in applications with high vibrations such as aircraft engine parts. As we are a leading manufacturer and supplier of these nuts, please feel free to contact us for different types such as the hex head barrel nut, other types and their pricing.
