Heavy Hex Nut
A Heavy Hex Nut is a larger and thicker version of the standard hex nut, offering greater strength and load-bearing capacity. With a wider across-flat dimension and increased thread engagement, heavy hex nuts are ideal for high-strength bolting applications in structural steel, heavy machinery, and industrial assemblies where extra durability is essential.
