Key Features of Our HT Bolts

• Made from high-grade alloy steel for superior tensile strength

Manufacturing Process – How We Ensure Quality

• Material Selection– Premium alloy or carbon steel rods are chosen based on required strength grade.
• Cutting & Heading– Bars are cut to length, and the bolt head is formed using cold or hot forging.
• Thread Rolling– Threads are rolled (not cut) for enhanced strength and uniformity.
• Heat Treatment– Controlled quenching and tempering improve hardness, tensile strength, and ductility.
• Surface Finishing– Protective coatings like zinc, galvanizing, or phosphate are applied for corrosion resistance.
• Quality Inspection– Dimensional checks, hardness tests, and tensile strength analysis ensure compliance with IS/ISO standards.
