 
				A galvanized heavy hex nut is a thicker, stronger version of a standard hex nut, designed for use in high-stress applications. Its larger size and increased thickness provide greater load-bearing capacity and resistance to wear, making it ideal for heavy machinery, construction, and industrial settings where secure fastening is critical.
