A490 Bolts

a490twoSimilar to the A325 ASTM standard, A490 bolts are used in steel to steel structural connections and applications and thus have shorter thread lengths than regular hex bolts. This keeps threads out of the joints in the connections. Unlike A325 bolts however, A490 bolts are made from an alloy steel (as opposed to the medium carbon steel used to make A325 bolts), making A490 bolts stronger, with a minimum 150ksi tensile strength. Sizes include 1/2″ thru 1 1/2″ diameter and up to 12″ long in some diameters.

Atlantic Bolt also has material test reports (MTRs) on file digitally for all our structural bolts.

(In 2016 the ASTM introduced the new umbrella specification F3125. F3125 encompasses six other ASTM standards, including A325, A325M, A490, A490M, F1852, and F2280. Currently, the F3125 specification is slightly less known and the A325, A325M, A490, A490M, F1852, and F2280 specifications are still how our customers refer to these bolts. As such, until the ASTM removes the A325, A325M, A490, A490M, F1852, and F2280 standards, we will continue to use the existing A325, A325M, A490, A490M, F1852, and F2280 specifications to reference these bolts.)
