What are the characteristics of heavy-duty hexagonal bolts?

The main characteristics of heavy-duty hexagonal bolts include high strength, high tensile strength, high temperature resistance, and good mechanical properties. Specifically:

● High strength: The tensile strength and yield strength of heavy-duty hexagonal bolts are both at a high level. Its tensile strength is usually not less than 1000MPa, and its yield strength also reaches above 900MPa. This means that the bolt can withstand significant external forces without fracture or obvious plastic deformation when subjected to tensile and other loads.

● High tensile strength and high temperature resistance: For example, A194 2H heavy-duty hex nuts are made of high hardness alloy steel and undergo heat treatment (such as quenching and tempering) to improve their strength and durability. This processing can improve the surface hardness and core strength of the nut, thereby extending its service life and enhancing reliability.

● Mechanical performance: The hardness of heavy-duty hexagonal bolts is moderate, generally measured by Rockwell hardness (HRC), with a hardness value between 32-39 HRC. This moderate hardness makes the bolt less likely to be damaged during tightening, while also effectively resisting wear and scratches from external hard objects, ensuring the long-term stability of its external dimensions and connection performance.

● Applicable scenarios: Heavy duty hexagonal bolts are widely used in situations that require high-strength connections, such as large machinery and equipment, highway bridges, high-rise buildings, etc. Its stable connection and efficient construction method make it outstanding in these fields.
