Anti-slip hex allen tool
A hex headed bit and socket for enhanced non-slip application of torque force having a hex head with contoured fastener engagement surface channel at the center of the respective alternating flat tool engagement sides. The contoured channels are tapered both transversely and longitudinally and extend in angular inclination across hex head bit flat side. The defined primary channel lateral edges correspondingly embed themselves during rotational engagement within the so engaged fastener pulling the hex head bit into the engaged fastener imparting enhanced translateral points of tool engagement.
1. An omni-directional multi-grip socket bit for hexagonal fasteners comprising,
a screw bit body having a fastener engagement free end portion and a tool engagement end portion,
a plurality of flat fastener engagement surfaces about said fastener engagement free end portion defining a hexagonal engagement shank,
at least one contoured fastener engagement channel cut transversely in at least one of said flat fastener engagement surfaces defining a first and second lateral fastener engagement edges,
a contoured transverse tapered interior surface extending between said channel cut's lateral edges,
said fastener engagement channel cut in angular orientation to the longitudinal axis of said tool engagement portion, said first lateral fastener engagement edge defining an interior fastener engagement surface in spaced relation to said second lateral edge.
2. The omni-directional multi-grip socket bit for hexagonal fasteners set forth in claim 1 wherein said elongated fastener engagement channels first and second lateral fastener engagement edges extend in tapered parallel relation to one another between longitudinal intersections of said respective adjacent flat fastener engagement surfaces.
3. The omni-directional multi-grip socket bit for hexagonal fasteners set forth in claim 1 wherein said respective engagement channel cut is in axially inwardly spaced relation to said multi-grip socket tool engagement free end portion.
4. The omni-directional multi-grip socket bit for hexagonal fasteners set forth in claim 1 wherein said fastener engagement channel cut contoured transverse tapered interior surface defines a sloping transverse C-shaped configuration.
5. The omni-directional multi-grip socket bit for hexagonal fasteners set forth in claim 4 wherein said fastener engagement contoured C-shape configured interior transverse taper extends from the primary elongated fastener engagement lateral edge upwardly to the secondary engagement lateral edge.
