Metal nuts are internally threaded mechanical fasteners designed to mate with bolts or threaded rods to generate precise clamping forces through elastic deformation and thread friction. They are manufactured to strict property classes and proof load ratings using materials such as carbon steel, stainless steel, and high-temperature alloys like Inconel. Essential for structural integrity, these fasteners are universally applied across aerospace assemblies, automotive chassis, civil infrastructure, and industrial machinery to manage extreme static and dynamic tensile loads.
