ASTM A490 Type 1 is a high tensile bolting grade manufactured from high tensile alloy steel intended for use in structural connections. Type 1 Bolts are produced from 1/2″ to 1-1/2″ in imperial size as per ASTM A490 & from M12 to M36 in metric size as per ASTM A490M. These A490 type 1 bolts can be supplied with zinc, cadmium or dacromet coatings in accordance to ASTM F1136. Ferrobend stocks raw material for quick manufacturing and shorter delivery times. We supply Type 1 boltings with EN 10204 type 3.1 certification.
