High tensile bolts are utilised in high-stress fastening applications. In the industrial environments related to building, for instance, high tensile bolts are widely utilised. For many years or perhaps decades, these sturdy bolts maintain the weight of enormous items by keeping them together and bearing their weight.

How to Identify the Differences Between High Tensile Bolt Grades

The grade or strength of a fastener may usually be ascertained by looking at the marks on the bolt’s head. English bolts (U.S.S. or S.A.E.) come in grades ranging from grade 2 to grade 8, where grade stands for inch strength.

Different ASTM Bolt Types

  • ASTM A320 Grade L7 BoltsASTM A320 Grade L7 Bolts is a material specification for bolts, studs, nuts, and other fasteners that can withstand high temperatures. Each of the four property classes—A, B, C, and D—in ASTM A320 Grade L7 has its own unique set of tensile and stress rupture properties.
  • ASTM A320 Grade L7A BoltsASTM A320 Grade L7A Bolts is a material specification for alloy steel bolting materials used on valves, flanges, and fittings for low-temperature pressure vessels.
  • ASTM A320 Grade L7B BoltsASTM A320 Grade L7B Bolts Material is heat treated to attain the qualities specified in ASTM A453 standard and is chemically identical to ASTM B638 grade 660 stainless steel alloy, commonly known as alloy A286 and UNS S66286. Chromium-molybdenum alloy steel with notch toughening and heat treatment is known as ASTM A320 Grade L7B (AISI 4140/AISI 4140H).
  • Astm A193 B7 Bolts : Astm A193 Grade B7 Bolts is a material standard for bolts, studs, nuts, and other fasteners that can withstand high temperatures. This grade has a minimum Charpy impact value of 20 ft. lbs. at minus 150° F, which is the lowest temperature at which it is intended to be used.
