ABSTRACT An improved high torque driving tool and high torque fastener and driving tool system is provided. The improved driving tool includes a conical tip formed centrally on an arcuately convex blade with a substan- tially pointed end projecting beyond the blade, wherein the blade and tip provide geometric surfaces for facili- tated and aligned centering and coaxial mating reception into the fastener driving slot and conical recess. The high torque fastener is of the type having a screw head with a generally bow-tie shaped driving slot formed with undercut side walls and an arcuately concave bottom wall for reception of an arcuately convex blade of a driving tool for relatively high torque transfer therebetween. The fastener includes a conical recess positioned cent- rally along the driving slot with a base diameter sub- stantially greater than the width of the slot thereat and an apex disposed substantially below the slot bottom wall. Apparatus for forming the improved fastener is also disclosed.
