Caliber Enterprise is a trusted high-quality heavy hex nuts manufacturer. These nuts are larger and thicker than standard hex nuts, designed for structural and high-load applications. Made from premium materials such as alloy steel, carbon steel, and stainless steel, heavy hex nuts deliver superior strength, durability, and resistance to vibration and stress. They are widely used in construction, oil & gas, wind energy, heavy equipment, and infrastructure projects. Available in metric and imperial threads (UNC, UNF), these nuts are manufactured to global standards like ASTM A194, ASTM A563, ASME B18.2.2, and DIN 934.

Customization options include surface treatments such as zinc plating, hot-dip galvanizing, black oxide, and PTFE coating. Each nut undergoes quality checks for thread precision, tensile load, and dimensional accuracy. Our products are listed on leading B2B trade portals, enabling bulk orders and seamless access for domestic and international buyers. With export-grade packaging and global shipping capabilities, we ensure prompt delivery and reliable service worldwide for critical structural fastening requirements.
