These specialists transform raw steel wire or bars into precise fasteners for Construction, Railways, and Industrial use. Key Manufacturing Processes Cold Forging (Cold Heading): Commonly used for high-volume, standardized bolt production. Steel wire is drawn, cut to length, and moulded into the bolt shape using high pressure at room temperature, which increases strength. Hot Forging: Used for larger or custom bolts. A round steel bar is heated to roughly 2000°F and forged into a hexagonal head using a National Upsetter. Thread Rolling: A cold forming process where threads are formed by rolling the bolt blank between dies, ensuring better fatigue resistance than cutting threads. Heat Treatment: Bolts are quenched and tempered to enhance hardness and tensile strength. Surface Treatment: Coatings such as zinc-plating or hot-dip galvanizing are applied to prevent corrosion. Typical Stages of Production Cutting: A round bar is cut to the required length. Heading: The bolt head is formed via hot or cold forging. Threading: Threads are cut or rolled onto the shaft. Heat Treatment: Strengthens the bolt. Finishing: Coating or galvanizing. Types of Manufacturers Industrial Manufacturers: Produce large volumes of standard, high-tensile fasteners (e.g., 8.8 or 10.9 grade) for infrastructure. Custom/Job Shops: Produce specific, non-standard, or large-diameter anchor bolts. Small-Scale Operators: Use smaller, versatile machines for customized or quick-turnaround production. Materials used typically include stainless steel, carbon steel, and alloy steel.
