Product Description

Before its discontinuation in 2016, the illustrious ASTM A490 specification provided guidance for quenched and tempered, high-performance alloy steel. These encompass heavy hex structural bolts crafted for resilience and reliability. Ranging from diameters of 1/2″ to 1-1/2″, these bolts boast a minimum tensile strength of 150 ksi. They are meticulously engineered for structural connections, possessing shorter thread lengths compared to standard hex bolts. For specific thread lengths and dimensions, kindly explore the Structural Bolts page on our website. A490 bolts, crafted from robust alloy steel, offer enhanced strength compared to A325 heavy hex structural bolts made from medium carbon steel. The A490 specification is exclusively for heavy hex structural bolts. For alternative thread lengths with akin mechanical properties, refer to Specification A354 grade BD for unparalleled performance.ASTM A490 bolts must not undergo hot-dip galvanizing, mechanical deposition, or zinc electroplating due to the risk of hydrogen embrittlement. However, ASTM has sanctioned the coating of A490 bolts with Zinc/Aluminum Corrosion Protective Coatings in accordance with ASTM F1136 Grade 3, commercially known as Geomet. Additional scrutiny, including Magnetic Particle Inspection for detecting longitudinal and transverse cracks, is mandated by the A490 specification.
