Product Description

Before its retirement in 2016, the distinguished ASTM A490 specification was the benchmark for robust, quenched and tempered alloy steel. heavy hex structural bolts, a key component in structural engineering. Ranging from 1/2″ to 1-1/2″ in diameter with an impressive minimum tensile strength of 150 ksi, these bolts are meticulously engineered for structural connections. They feature shorter thread lengths compared to standard hex bolts, aligning with their specialized application. To explore thread lengths and related dimensions, visit the Structural Bolts section on our website. A490 bolts are akin to A325 heavy hex structural bolts, distinguished by their alloy steel composition that promises superior strength compared to medium carbon steel alternatives. Note that the A490 specification is exclusive to heavy hex structural bolts. For bolts with variant thread lengths sharing similar mechanical properties, refer to Specification A354 grade BD, a comprehensive counterpart.It is crucial to note that ASTM A490 bolts are not to be galvanized, mechanically deposited, or zinc-electroplated due to potential hydrogen embrittlement. However, ASTM has sanctioned the use of Zinc/Aluminum Corrosion Protective Coatings, specifically ASTM F1136 Grade 3, known commercially as Geomet. Additionally, these bolts undergo rigorous testing, including Magnetic Particle Inspection for both Longitudinal Discontinuities and Transverse Cracks, as stipulated by the A490 specification.
