ABSTRACT:
Improved sockets for driving nuts and the like, the sockets having improved markings so that the proper size and type of each socket can be easily identified and selected, even under adverse conditions, and so that each socket can be readily returned to its proper location after use. This is accomplished by placing size markings on four (4) differing sides of a cylindrical socket, the size markings being spaced about 90.degree. apart. In addition, each of the sockets is color coded to facilitate reassembling the socket sets at the completion of work. In one example, colored plugs will be provided on each of the sockets either above or below the size markings. The sequence of colored plugs may repeat after three separate colors have been used if there is an obvious size difference between two sockets which are three sizes apart. In addition, the socket caddy is also be color coded. Finally, in order to distinguish between metric and english sockets, each socket is provided with a further identifying mark to indicate whether or not it is an english or metric socket. To this end, english sockets may be provided with 1 to 4 rings or grooves on the open end of the socket, i.e., the end of the socket which receives the nut to be driven, whereas metric sockets would be provided with 1-4 rings or grooves of the opposite end.
