Product Description

Before its retirement in 2016, the renowned ASTM A490 specification was the benchmark for quenched and tempered alloy steel. This specification included heavy hex structural bolts. Ranging from 1/2″ to 1-1/2″ in diameter, these bolts boast a formidable minimum tensile strength of 150 ksi. Specifically crafted for structural connections, they feature shorter thread lengths than standard hex bolts. Discover precise thread lengths and detailed dimensions on our website's Structural Bolts section. A490 bolts stand out as premium, high-strength fasteners, akin to A325 heavy hex structural bolts in use and size but superior due to their alloy steel composition. Note that the A490 specification applies exclusively to heavy hex structural bolts. For bolts requiring alternative thread lengths but retaining similar mechanical properties, refer to Specification A354 grade BD.ASTM A490 bolts are not suited for hot-dip galvanizing, mechanical deposition, or zinc electroplating due to hydrogen embrittlement risks. However, ASTM endorses coating A490 bolts with Zinc/Aluminum Corrosion Protective Coatings as per ASTM F1136 Grade 3, known commercially as Geomet. Additionally, A490 specification mandates extra testing through Magnetic Particle Inspection to detect Longitudinal Discontinuities and Transverse Cracks.
