ABSTRACT:
Described is a combination of fasteners and tools which visually communicate their respective sizes to the user so clearly that by merely glancing at these objects a tool matching the fastener or a fastener that matches the tool can readily be selected for use. This beneficial result is achieved by visually coding the fasteners of different sizes either by a pattern or preferably by color so that all fasteners of a given size bear one distinguishing visual appearance, all fasteners of another given size bear another distinguishing visual appearance, and so on.
