Metal hardware businesses supply products made from metal for construction, repair, manufacturing and general use. Their stock may include screws, bolts, nuts, washers, nails, hinges, brackets, handles, hooks, chains, locks, fasteners and fittings. Some suppliers also carry tools, fixings and accessories for working with or installing these items. Customers can typically choose from different materials, finishes, sizes and grades, such as steel, stainless steel, brass or aluminium, depending on the product and its intended use. Businesses may supply standard components for household repairs as well as specialist hardware for tradespeople, workshops and industrial applications. Some offer help identifying compatible fittings, cutting or preparing metal products, or sourcing less common items. Many serve both trade and retail customers, with availability and services varying by supplier.
