The main standards for high-strength bolts are as follows

1. GB/T 1231-2006 "High strength Hex bolts, Hex nuts and washers" : This is the main standard of China's national standard for high strength hex bolts, hex nuts and washers, which specifies the product classification, representation, order content, materials, heat treatment, mechanical properties, dimensions, tolerances, test methods, inspection rules, marking, packaging, transportation and storage The content. 2. GB/T 3098.1-2010 "Mechanical properties Test Method" : This standard is suitable for the mechanical properties test of high-strength bolts. 3. JGJ82-2011 "Steel structure high-strength bolt friction surface anti-slip design and construction code" : This is a code prepared by the China Academy of Building Science, mainly applicable to the use of high-strength bolt connection steel structure design and construction. It should be noted that the above standards are only general standards, and different industries and fields may have their own specific standards or specifications. When selecting high-strength bolts, it is also necessary to select products that meet the relevant standards according to the specific use environment and requirements.
