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.
