High Strength Heavy Structural ASTM A490 Type 3 heavy hex bolt

ASTM A490 bolts are heavy hex bolts made of alloy steel with a flat bearing surface, washer faced, and chamfered point. They are used in structural steel joints in heavy construction applications that require greater yield and tensile strengths than those of an A325 bolt are required. They are available in diameters ranging from ½” up to 1-1/2” and come in two types. Type 1 bolts are made from alloy steel, and Type 3 is made from a weathering steel, which is approximately twice as resistant to corrosion as Type 1. These Type 3 A490 bolts shall be marked “A490” to set them apart from standard A490 bolts.
