Bolts and nuts are used in a host of applications in almost all industrial applications. There are different standards and specifications for the bolts and nuts to specify their properties and attributes. The ASTM A193 Grade B7 Bolts are made up of a chromium molybdenum material that has high tensile strength and good elongation properties. The ASTM A193 gr b7 bolts can come in a B7M specification as well.
This is useful to select the bolts for different high pressure and high temperature applications with different strength levels needed. The ASTM A193 grade b7 stud bolts and other types have minimum tensile strength up to 125ksi. The smaller diameter bolts have the highest strength values. The B7M grades have lower tensile strength up to 100ksi. The ASTM A193 grade b7 anchor bolts are used to hold a component anchored onto another surface. They can range up to 105ksi in minimum yield strength. There are different types of bolts and nuts to suit for different types of applications such as the ASTM A193 gr b7 stud bolt. The stud bolts are essentially threaded rods. There are also different varieties of the stud bolt types. The B7 stud bolts have high hardness with 321HBW max while the B7M variation has less hardness of 235HBW max.
There are slight mechanical differences to the two grades of bolts. Hardness testing requirements are also different for both grades. B7M Yield is about 20% less compared to B7, the B7 Bolts Torque will higher from Grade B7M.

The ASTM A193 grade b7 threaded rod is used in applications where both components have threads and the fitting is by means of nuts. So there is no need for a head on the bolt.
