Official abstract text for this publication.
A screw bit body allows for efficient torque force application onto a socket fastener. The screw bit body includes a plurality of laterally-bracing sidewalls, a first base, and a second base. The laterally-bracing sidewalls are radially distributed about a rotation axis of the screw bit body with each further including a first lateral edge, a second lateral edge, a first bracing surface, a second bracing surface, and an engagement cavity. The engagement cavity creates an additional gripping point to prevent slippage in between the screw bit body and the socket fastener. The engagement cavity traverses normal and into the screw bit body from the first base to the second base. The engagement cavity comprises a protrusion arranged between a first cavity section and a second cavity section.

What is claimed is: 1. An advanced holding apparatus, comprising: at least one screw bit body; the at least one screw bit body being a fully enclosed solid; the at least one screw bit body comprising a plurality of laterally bracing sidewalls; the plurality of laterally bracing sidewalls each comprising a first lateral edge, a second lateral edge, a first bracing surface, a second bracing surface, and at least one engagement cavity; the plurality of laterally bracing sidewalls being radially positioned about a rotation axis of the at least one screw bit body; the first lateral edge and the second lateral edge being positioned opposite one another about the respective laterally bracing sidewall; the at least one engagement cavity extending normal and into the screw bit body; the at least one engagement cavity comprising a plurality of cavity sections and at least one protrusion, wherein each of the plurality of cavity sections is concave and the at least one protrusion is convex; the at least one protrusion being arranged among the plurality of cavity sections; the plurality of cavity sections comprising a first cavity section and a second cavity section; the first cavity section being offset from the second cavity section by the at least one protrusion; an imaginary bracing plane extending parallel to the first bracing surface; a first cavity depth being the greatest distance from the imaginary bracing plane to the first cavity section, perpendicular to the imaginary bracing plane; a second cavity depth being the greatest distance from the imaginary bracing plane to the second cavity section, perpendicular to the imaginary bracing plane; a first cavity length being the shortest distance from the first bracing surface to the at least one protrusion across the first cavity section; a second cavity length being the shortest distance from the second bracing surface to the at least one protrusion across the second cavity section; the first cavity depth being greater than the second cavity depth or the second cavity depth being greater than the first cavity depth; and the first cavity length is longer or shorter than the second cavity length. 2. The advanced holding apparatus of claim 1 , further comprising: a midplane for each of the plurality of laterally bracing sidewalls being positioned on a cross section of the at least one screw bit body; the midplane being parallel to the first bracing surface; the midplane passing through the rotation axis; a protrusion distance being the greatest distance between the protrusion and the midplane, perpendicular to the midplane; and a bracing distance being the shortest distance between the first bracing surface and the midplane. 3. The advanced holding apparatus of claim 2 , wherein the protrusion distance is equal to the bracing distance. 4. The advanced holding apparatus of claim 2 , wherein the protrusion distance is greater than the bracing distance. 5. The advanced holding apparatus of claim 2 , wherein the protrusion distance is less than the bracing distance. 6. The advanced holding apparatus of claim 1 , wherein the plurality of cavity sections is rounded in shape. 7. The advanced holding apparatus of claim 1 , wherein the plurality of cavity sections is angular in shape. 8. The advanced holding apparatus of claim 1 , wherein the at least one protrusion is rounded. 9. The advanced holding apparatus of claim 1 , wherein the at least one protrusion is pointed. 10. The advanced holding apparatus of claim 1 , wherein the at least one protrusion is flat. 11. The advanced holding apparatus of claim 1 , wherein the at least one protrusion is arranged between the first cavity section and the second cavity section. 12. The advanced holding apparatus of claim 11 , further comprising: the first bracing surface being positioned adjacent to the first lateral edge; the first cavity section being positioned adjacent to the first bracing surface opposite the first lateral edge; the second bracing surface being positioned adjacent to the second lateral edge; and the second cavity section being positioned adjacent to the second bracing surface, opposite the second lateral edge. 13. The advanced holding apparatus of claim 1 , further comprising: a plurality of intermittent sidewalls; the plurality of intermittent sidewalls being radially positioned about the rotation axis of the at least one screw bit body; and the plurality of intermittent sidewalls being interspersed among the plurality of laterally bracing sidewalls. 14. The advanced holding apparatus of claim 13 , wherein the each of the plurality of intermittent sidewalls is flat. 15. The advanced holding apparatus of claim 1 , wherein the first bracing surface and the second bracing surface are parallel to one another.
