M16 White Black Zinc Nickel Plated Coated 12 Point Metal Bolts Iron ASTM A325 Mild Steel

These M16 12-point flange bolts are manufactured from mild steel in accordance with ASTM A325 specifications, ensuring they meet the rigorous demands of structural fastening. What sets this particular product apart is the advanced surface finish: a choice of White or Black Zinc-Nickel plating. Zinc-Nickel is a high-performance alloy coating that offers significantly superior corrosion resistance compared to standard zinc plating, often by a factor of 5 to 10 times. It provides excellent barrier and sacrificial protection to the underlying high-strength steel core. The bolt features a robust 12-point flange head, designed for high-torque installation and integrated load distribution, making it a heavy-duty fastener for demanding industrial and structural applications.

This bolt is specifically targeted at heavy industrial, infrastructure, and military applications where high strength and exceptional corrosion resistance are non-negotiable. The M16 size and ASTM A325 material make it suitable for structural steel connections in bridges, large buildings, and industrial plants located in harsh environments like coastal regions, chemical plants, or wastewater treatment facilities. The Zinc-Nickel coating is particularly valued in the automotive and defense industries for components exposed to road salts and severe weather, such as heavy truck frames, military vehicle assemblies, and earth-moving equipment. The choice of white or black finish allows for aesthetic matching or color-coding for assembly purposes.

The standout feature is the Zinc-Nickel plating, which provides vastly superior corrosion protection compared to traditional zinc coatings, ensuring long-term reliability in the most challenging environments. Conformance to the ASTM A325 standard guarantees the bolt's mechanical properties are suitable for critical structural connections. The M16 size offers substantial load capacity for heavy-duty applications. The 12-point flange head design allows for the application of high, precise torques, ensuring proper preload in the joint. The availability of both white and black finishes provides flexibility for both functional and aesthetic requirements, with the black finish also offering reduced glare in certain applications.
