SA 193 B7m Hex Bolt, Alloy Steel A193 B7m Stud and Threaded Rod manufacturer in India

What are ASTM A193 grade b7m bolts?

ASTM A193 b7m bolts belong to a specification that covers bolts of high tensile strength and hardness. The minimum yield strength required is 75ksi and the minimum tensile strength required is 100ksi. The hardness should be 99HRB. Rolex Metal Distributors is a leading manufacturer and supplier of the different types of ASTM A193 gr b7m bolts in different dimensions and standards. The specification covers the requirements of recommended nuts, heat treatment, hardness, mechanical properties and chemical composition of these bolts. The ASTM A193 gr b7m material has carbon, manganese, phosphorus, sulfur, silicon, chromium and molybdenum. It is a carbon steel with chromium and molybdenum content. So it has good strength, ductility, corrosion resistance and hardness as well. So the B7m bolts and nuts are used in extreme conditions without cracking under pressure or stress. They can perform up to the tensile strength of the material grades. The material grades used can be 304 and 316.

A193 b7m bolts coatings

ASTM A193 b7m bolts, studs, nuts are available with PTFE Coating, Hot Dip Galvanised, Xylan Coating, and Cadmium Coating.

ASTM A193 b7m stud bolt vs threaded rod?

The threaded rods of the same material grade are also used in applications. The bolts are better to be tightened in open space where the application of nuts is possible. The threaded rods are used when there is no space for nuts and two components have to connect closely. The application of the Stud Bolt astm a193 b7m can be seen in oil and gas, petroleum, petrochemical, marine, engineering, automobile and in transportation applications due to the toughness and hardness of the material. The material is also wear resistant to certain extent.

B7m hex bolts thread types?

There are different classes as class1 and class 2 with different thread types as well. The coarse thread and the fine thread types of the B7m fasteners are available as well. The recommended nuts for the B7M bolts are the ASTM A194 grade 2HM and the recommended washers are the F436. Please feel free to contact us for more information and pricing of the different types of the B7M bolts.
