Product Description

In a remarkable legacy before its withdrawal in 2016, the ASTM A490 specification encompassed the finely engineered quenched and tempered alloy steel, renowned heavy hex structural bolts, epitomizing strength and durability, ranging from an exacting 1/2″ to 1-1/2″ in diameter, boasting a formidable minimum 150 ksi tensile strength. Specifically designed for enduring structural connections, these bolts feature shorter thread lengths than standard hex bolts. We invite you to explore our Structural Bolts page for detailed thread lengths and comprehensive dimensions. While A490 bolts share similar applications and dimensions with A325 heavy hex structural bolts, their distinct composition of alloy steel over medium carbon steel offers a superior strength advantage. The A490 specification is exclusively tailored for heavy hex structural bolts. For variations in thread lengths that deviate from standard structural bolts yet retain comparable mechanical attributes, consult the Specification A354 grade BD.It is essential to note that ASTM A490 bolts are prohibited from being coated with hot-dip galvanizing, mechanical deposition, or electroplating with zinc to avert the risk of hydrogen embrittlement. The ASTM has sanctioned the use of Zinc/Aluminum Corrosion Protective Coatings, specifically ASTM F1136 Grade 3, known commercially as Geomet, for these bolts. Furthermore, the A490 specification mandates additional testing, including Magnetic Particle Inspection for detecting Longitudinal Discontinuities and Transverse Cracks, ensuring utmost reliability.
