ASTM A325 Bolts McMaster-Carr

Medium-Strength Steel Heavy Hex Head Screws for Structural Applications Fully Threaded Partially Threaded The most common heavy hex head screw, these steel screws meet ASTM A325 regulations for structural joints, such as mating I-beams and scaffolding. Material meets ASTM F3125 specifications for quality. ASTM Bolts McMaster-CarrMade from 316 stainless steel, these Grade B8M screws are more corrosion resistant than 18-8 stainless steel screws and have excellent resistance to chemicals and salt water. Screws meet ASTM A193 regulations, so they can be used in high-pressure and high-temperature applications. Also known as pressure bolts. Structural Bolts McMaster-CarrUse them in joints that require more tensile strength than ASTM A325 screws. Carriage Bolts Medium-Strength Grade 5 Steel Square-Neck Carriage Bolts Twice as strong as low-strength steel bolts, these bolts are suitable for fastening most machinery and equipment. Carriage bolts have a smooth, rounded head for a finished look. Galvanized Steel Hex Nuts for ASTM Bolts These nuts are designed to secure ASTM A325 bolts in structural joints. Also known as heavy hex nuts, they are about 10% wider and taller than standard hex nuts and distribute the load over a large area. Hot-dipped galvanized steel nuts have a thick coating for good corrosion resistance. They must be used with other hot-dipped galvanized fasteners. Bolts McMaster-Carr
