To keep them from rusting, high precision Weld hexagon nuts with flange are usually electroplated with zinc. This zinc coating often clear, yellow, or black chromated,acts like a protective layer that takes the damage instead, making them hold up better against the environment. Zinc-plated ones offer decent rust protection and don’t cost too much, which works for a lot of industrial settings.
For better rust protection in tough places,like marine areas, around chemicals, or outdoor structures high precision Weld hexagon nuts with flange get hot-dip galvanized.This process coats the entire nut, including the critical flange base and welded areas, with a dense zinc-iron coating that lasts even in high-humidity, salty environments.

High precision Weld hexagon nuts with flange usually come in metric (ISO) and imperial (UNC/UNF) thread sizes. Common sizes go from M4/M5 up to M24, or 1/4" up to 1". Exactly what’s available depends on who makes them and what material grade you need.
