High-Quality Galvanized Nut Manufacturer

Galvanized nuts produced by Ningbo Mohai Fasteners Co., Ltd. are precision fasteners that combine high-strength connections with excellent corrosion resistance. They are made from high-quality carbon steel and stainless steel substrates through multiple processes, suitable for fastening needs in various fields such as machinery manufacturing, construction engineering, power equipment, and the automotive industry.

Key advantages: The surface is treated with hot-dip galvanizing/electro-galvanizing, resulting in a uniform and dense zinc layer with strong adhesion. Salt spray testing can reach 48-96 hours, effectively resisting corrosion from harsh environments such as humidity and acids/alkalis, extending service life. Precision rolling ensures clear and regular threads with tolerances controlled within ±0.01mm, providing a tight fit and eliminating the risk of stripping. When used with bolts, the connection is stable. The substrate undergoes heat treatment, achieving a hardness of HRC30-40 and a tensile strength ≥600MPa, meeting industrial-grade high-strength fastening requirements.

Specifications cover the full range from M3 to M24, supporting customized surface treatments such as galvanizing, color zinc plating, and Dacromet coating to meet different application needs. Our products strictly adhere to ISO9001 standards and undergo multiple inspections, including material testing, dimensional accuracy verification, and corrosion resistance testing, resulting in a 100% factory pass rate. With high reliability, strong adaptability, and cost-effectiveness, they have become the preferred corrosion-resistant fastener solution for customers both domestically and internationally.
