ASTM A325 Grade 5, A490 Grade 8, DIN 6914 8.8 & 10.9 HDG Structural Heavy Hex Bolts and Nuts
A bolt is a type of threaded fastener with an external male thread, often confused with screws. Heavy hex structural bolts are specifically designed for steel-to-steel connections in construction and engineering applications. They are typically short and have shorter thread lengths compared to standard hex bolts. ASTM A325 and A490 standards cover high-strength heavy hex structural bolts ranging from 1/2" to 1-1/2" in diameter, primarily used in structural connections. These bolts are not intended for general-purpose use.
