The markings on a bolt head indicate its grade, material, and strength. These markings typically include numbers, symbols, or letters that denote the bolt's tensile strength and other mechanical properties. For example, a bolt marked with "8.8" signifies a medium carbon steel with a specific tensile strength, while additional markings can indicate the manufacturer's code or specific standards met. Understanding these markings helps in selecting the appropriate bolt for a given application.
