Abstract
A socket driver, and method of forming the same, is described in which longitudinal protuberances are provided on successive surfaces of the hexagonal cavity for receiving a bit driver. The protuberances create an interference fit with the driven end of the bit driver, the protuberances being so dimensioned that forceful insertion of the bit driver into the hexagonal cavity at least partially deflects the walls portions on which protuberances are formed to thereby slightly deflect the same. The resulting restoring forces create a spring action which semi-permanently secures the bit driver received within the socket driver.
