Custom Lost Wax Casting Part Carbon Steel Heavy Duty Bolt and Nut Set

This heavy-duty bolt and nut set is manufactured from high-carbon steel using the lost wax casting method, engineered for extreme load and shock conditions in industrial applications. Precision casting ensures full thread profiles without root defects, along with dense, uniform material structure in the bolt head and nut bearing surfaces. The set can be quenched and tempered, and includes surface treatments such as galvanizing or black oxidizing for enhanced tensile strength, fatigue resistance, and corrosion protection. Available in customizable sizes (e.g., M12 to M64) and property classes, it is ideal for critical connections in heavy machinery, structural steelworks, mining equipment, and marine engineering where high strength and long-term reliability are essential.
