A-490 Structural Bolts


A-490 or A490 structural bolts are heavy-duty fasteners commonly used in high-strength structural steel connections or structural bolting projects such as construction and bridge work. While A-490 bolts cannot be galvanized due to the risk of hydrogen embrittlement, they are stronger than other structural steel fasteners, such as A325 bolts.


A490 bolts have standard diameters ranging from 0.5” to 1.5” and are made from Type 1 high-carbon alloy steel or Type 3 weathering steel for high tensile strength. Type 3 steel is meant to weather and rust as it ages, forming a protective coating that further seals and strengthens the bolt.
