ASTM A490M BOLT
10 month ago
Yokelink ASTM A490 Structural Bolts are a specialized heavy type of hex bolt intended for use in large structures, such as buildings and bridges. This bolt is designed to withstand the loads of steel-to-steel structural connections. They contain a flat, washer-faced bearing surface and a chamfered thread point. Galvanized plating protects the bolt from corrosion; typically used in outdoor applications.
ASTM A490 and ASTM A490M are ASTM International standards for heavy hex structural bolts made from alloy steel.The imperial standard is officially titled Standard Specification for Structural Bolts, Alloy Steel, Heat Treated, 150 ksi Minimum Tensile Strength, while the metric standard (M) is titled Standard Specification for High-Strength Steel Bolts, Classes 10.9 and 10.9.3, for Structural Steel Joints.In 2016, specifications A325 and A490 were officially withdrawn by ASTM and replaced by ASTM F3125. A325 and A490 heavy hex structural bolts are now grades under the new F3125 specification.
