High Strength M10 ASTM A325M grade 8.8 zinc plated heavy hexagon bolt
ASTM A325 structural bolts are heavy hex bolts made of medium carbon steel with a flat bearing surface, washer faced, and chamfered point. They are commonly used in structural steel joints in heavy construction and available in diameters ranging from 1/2” up to 1-1/2”. A325 structural bolts come in two types. Type 1 is a medium carbon steel and can be galvanized; Type 3 is a weathering steel that offers additional corrosion resistance. These Type 3 A325 bolts shall be marked “A325” to set them apart from standard A325 bolts.
