Product Description

Before its withdrawal in 2016, the celebrated ASTM A490 specification was the benchmark for quenched and tempered alloy steel, heavy hex structural bolts, known for their resilience and robustness. Ranging from 1/2″ to 1-1/2″ in diameter, these bolts boast a minimum tensile strength of 150 ksi. Crafted for structural connections, they feature shorter thread lengths compared to standard hex bolts. Discover detailed thread lengths and more on our Structural Bolts page. While A490 bolts share applications and dimensions with A325 heavy hex structural bolts, they shine with superior strength due to their alloy steel composition. This specification is exclusive to heavy hex structural bolts. For variants with unique thread lengths yet similar mechanical prowess, refer to Specification A354 grade BD for other options.ASTM A490 bolts are spared from coatings via hot-dip galvanizing, mechanical deposition, or electroplating with zinc, to avoid hydrogen embrittlement risks. Approved by ASTM, Zinc/Aluminum Corrosion Protective Coatings per ASTM F1136 Grade 3, known commercially as Geomet, safeguard these bolts. Moreover, stringent Magnetic Particle Inspection for Longitudinal Discontinuities and Transverse Cracks is mandated under the A490 specification.
