Socket screws with internal drives came into existence over 100 years ago and developed along with the Holo-krome, Allen and Unbrako brand names.
Acceptance of the internal-wrenching hexagon drive was slow in its adoption first being taken up for tool and die work and then in manufacturing; after 1945 the socket family came into widespread use. During the 1970’s the brand control of the global market declined with the introduction of socket screws from Europe rapidly followed by Japan and currently Taiwan and India.
