Product Description

Before its retirement in 2016, the prestigious ASTM A490 specification comprehensively detailed the requirements for quenched and tempered, high-performance alloy steel. heavy hex structural bolts, renowned for their robust construction and reliability. These bolts, available from 1/2″ to 1-1/2″ in diameter, boast a minimum tensile strength of 150 ksi. Tailored for structural connections, they feature reduced thread lengths compared to standard hex bolts. Explore our Structural Bolts page for precise thread lengths and additional dimensional details. Distinguished by their alloy steel composition, A490 bolts offer superior strength compared to A325 heavy hex structural bolts, which utilize medium carbon steel. It's important to note that this specification solely pertains to heavy hex structural bolts. For components requiring different thread lengths but maintaining similar mechanical attributes, refer to Specification A354 grade BD.It's crucial to remember that ASTM A490 bolts must not undergo hot-dip galvanizing, mechanical deposition, or electroplating with zinc, due to the risk of hydrogen embrittlement. Nonetheless, ASTM has sanctioned Zinc/Aluminum Corrosion Protective Coatings according to ASTM F1136 Grade 3, commercially known as Geomet, for A490 bolts. Moreover, additional testing, including Magnetic Particle Inspection for Longitudinal Discontinuities and Transverse Cracks, is mandated by the A490 specification.
