Abstract: A hex headed bit and socket for enhanced non-slip application of torque force having a hex head with contoured fastener engagement surfaces. The contoured fastener engagement surface extends transversely in angular longitudinal inclination. Defined multiple engagement 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 for extraction. Recessed areas on flat hexagonal free end tool portion defining alternate spaced pairs of parallel engagement edges.

Abstract: A hex headed bit and socket for enhanced non-slip application of torque force having a hex head with contoured fastener engagement surface channels in the respective alternating flat tool engagement sides and tapered step end engagement surfaces with fastener engagement edges. The contoured channels are tapered both transversely and longitudinally and extend in angular inclination across hex head bit flat side. Alternate alternating recess areas in a hexagonal insertion bit defining pairs of spaced parallel vertical engagement edges. The defined primary channel lateral edges and correspondingly end engagement surface engagement edges and vertical engagement edges 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.

Abstract: An improved open-ended wrench that is adaptable for engaging hexagonal head nuts with non-specific engagement surfaces. The wrench provides a handle with an open working end having opposed flat jaw working surfaces with a positional work piece engagement cavity there between. A contact enabling contoured notch cutout in each flat inside working surface with corresponding standard and non-standard support and torque engagement surface respectively inwardly from the junction of the concave cavity portion.

Abstract: 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.
