五金店是指专门售卖油漆、螺丝钉子、水喉配件等器具的店铺。新式家品店因为也售卖电器、厨房用品、床上用品等，它们的目标客人有所分别，所以未必能取代五金店。五金店卖的称为半制成品耗材和建筑业工具。

许多五金店依据所在地和客户群的兴趣设有专供部门，售贩的东西包括打猎钓鱼工具、船上用品、宠物食品和农场用品等。目前世界上最大的四家五金零售店分别是The Home Depot（美国）、Lowe's（美国）、Kingfisher（英国）和Obi（德国）。

Ironmongery originally referred, first, to the manufacture of iron goods and, second, to the place of sale of such items for domestic rather than industrial use. In both contexts, the term has expanded to include items made of steel, aluminium, brass, or other metals, as well as plastics.
