ASTM A193 B7m Threaded Rod and SA 193 B7m Stud Bolt as per ASME/ UN/ DIN/ ISO standards & CE Marking

Distinctive differences are found when comparing both b7m material and b7 starting from their tensile strength.

  • For diameters under 4inches, B7M has 100 ksi tensile strength whereas for b7 it has 125 ksi minimum tensile strength for less than 2-1/2 inches, and for diameters with less than 2-1/2in-4in it shows 115 ksi minimum tensile strength.
  • Another difference lies in their hardness. A193 GR B7m Hex Bolts has more hardness than b7 with the value of 235 or 99 HB.
  • On the basis of manufacturing process, when we are supplying bolts b7m, they are tested individually for their hardness.
  • B7m is often used in the construction fields because of its maximum hardness.

Before ordering a SA 193 B7m Stud Bolt, it is important that we first have our specifications ready. If you are sure with your specification, specify your requirements to the manufacturer. You can provide data such as:

  • Total Length.
  • Threading length.
  • Specify 3 types of diameters: major, pitch and minor.
  • Chamber
  • Thread per inch.

Based on the above-mentioned data, it helps the manufacturer to get an idea about what the customer. Also, before purchasing the bolt, you can enquire about the product by asking the dimensions as per ASTM b18.1.1, physical and chemical properties as specified in ASTM A193. In this way, both the manufacturer and the purchaser have a clarity of what is their need.
