This set of 9 Facom Inch Hex keys are handy for when it\'s not possible to carry a heavy load of tools around, or even if you simply don\'t want too. This set includes nine different sizes, so there is a tool for most jobs and all nine are stored in a folding key set, for easy storage and transport. However, despite being so portable and lightweight, there is no loss in quality. The keys are manufactured from zinc-plated chrome steel, so they are tough and durable.
