Nuts
What are Nuts?
Nuts are internally threaded fasteners designed to mate with bolts, screws, or studs, creating a secure and detachable joint. They are used across a wide range of industries to clamp components together and provide structural stability in machines, assemblies, and frameworks. Available in various materials like carbon steel, alloy steel, brass, and more, nuts come in multiple shapes and designs to suit different engineering and installation needs.
Whether used in automotive manufacturing or heavy structural projects, nuts offer reliable fastening strength and compatibility with a wide range of threaded components.
