Precision Engineered Welding flange nut come in different colors and surface looks—it all depends on the material they’re made of and the coating used on them.These nuts usually have a few common surface finishes:Silver ones: They’re zinc-plated (meaning a layer of zinc is added to the surface).Yellow ones: They have a zinc chromate finish (treated with zinc chromate to get that color).Black ones: They’re phosphated (coated with a phosphate layer for the black look).There’s also plain stainless steel—this one just keeps the original color of stainless steel, with no extra coating.
Besides fighting rust, the coatings also give a cleaner appearance and help tell different specs apart. Using color coding makes it easier to manage stock and grab the right nut faster during assembly.
The surface finish also improves grip and helps the nuts weld on better, so they stay firmly in place. So the color and coating aren’t just about looks—they actually make the nut more practical and easier to use.

A:For a secure bond, the surface must be clean. Position the Precision-Engineered Welding flange nut and use a continuous circular weld around the flange's base. Avoid excessive heat to prevent thread distortion. Always consult specific welding procedure specifications for your material.
