Drive system configured to provide frictional fit engagement

A drive system comprising:

• a drive bit comprising a drive portion and a pilot end which extends from the drive portion and ends at a pilot end surface, the drive bit comprising
• a pilot end longitudinal axis, and
• an outer leading wall that is tapered with respect to the pilot end longitudinal axis to define a leading wall angle selected from a plurality of leading wall angle values ranging within a leading wall angle tolerance band;
• and
• a fastener having
• an internal pilot recess that receives the drive bit, the internal pilot recess having a recess longitudinal axis, and
• an inner pilot recess wall that is tapered with respect to the recess longitudinal axis to define a recess wall angle selected from a plurality of recess wall angle values ranging within a recess wall angle tolerance band,
• wherein the plurality of leading wall angles within the leading wall angle tolerance band and the plurality of recess wall angles within the recess wall angle tolerance band do not overlap when the outer leading wall of the pilot end contacts the inner pilot recess wall along a circumferential line of contact at a targeted focal area at a bottom of the outer leading wall proximate the pilot end surface to achieve a desired level of frictional engagement between the pilot end and the fastener wherein the outer leading wall has a circular cross section at the targeted focal area to provide the desired level of frictional engagement between the pilot end and the fastener.
