  • Drive system configured to provide frictional fit engagement
    Patent number: 11926021
    Abstract: A drive system including a bit with a bit end configured to provide targeted frictional engagement with a fastener. The bit end has an outer leading wall tapered with respect to the bit end longitudinal axis at a leading wall angle selected from leading wall angle values ranging within a leading wall angle tolerance band and the fastener has an inner recess wall tapered with respect to the fastener longitudinal axis at a recess wall angle selected from recess wall angle values ranging within a recess wall angle tolerance band, wherein the leading wall angle values within the leading wall angle tolerance band and the recess wall angles values within the recess wall angle tolerance band do not overlap when the outer leading wall contacts the inner pilot recess wall at a targeted focal area to achieve a desired level of frictional engagement between the pilot end and the fastener.
