Abstract
The present invention relates to tools, for example, hexagonal drivers and bits adapted to engage fasteners. The tool includes an external geometry that is adapted to engage internal walls or flats of a fastener with a larger area compared the prior designs that use a point type of contact. This reduces the stress exerted on the fastener and damage or deformation to the internal walls of the fastener.
