ASTM A325 Grade 5, A490 Grade 8, DIN 6914 8.8 and 10.9 HDG Structural Heavy Hex Bolts and Nuts
A bolt is a threaded fastener with an external male thread, often used in conjunction with nuts to secure two or more components together. Heavy hex structural bolts are specifically designed for steel-to-steel connections in construction and engineering applications. These bolts are typically short with a limited thread length, making them ideal for structural joints. ASTM A325 and A490 standards define high-strength heavy hex bolts ranging from 1/2" to 1-1/2" in diameter, primarily intended for use in critical structural connections. They are not recommended for general-purpose applications.
