What must identification markings for high-strength bolts, nuts, and washers conform to according to construction documents?

The identification markings for high-strength bolts, nuts, and washers are required to conform to ASTM (American Society for Testing and Materials) standards as specified in construction documents. ASTM provides essential guidelines and specifications that ensure the quality and performance of materials used in construction. This includes critical information pertaining to mechanical properties, chemical composition, and the testing methods necessary for these fasteners.

Compliance with ASTM standards assures that the high-strength components meet rigorous safety and performance criteria, which is vital for structural integrity in construction projects. In this context, failure to adhere to these standards could compromise the reliability and safety of structures, emphasizing why ASTM is the appropriate reference for identification markings related to high-strength fasteners.
