Abstract

A screw bit body which 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 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 bracing surface. Additionally, the engagement cavity traverses into the screw bit body from the first base to the second base. The engagement cavity is specifically positioned offset from the first lateral edge by a first distance.

First claim

What is claimed is:

1. An advanced holding apparatus comprising:
at least one screw bit body;
an attachment body;
the at least one screw bit body comprising a plurality of laterally-bracing sidewalls, a first base, and a second base:
each of the plurality of laterally-bracing sidewalls comprising a first lateral edge, a second lateral edge, a bracing surface, and at Last 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 to each other across the bracing surface;
the at least one engagement cavity extending normal and into the bracing surface;
the at least one engagement cavity extending into the at least one screw bit body from the first base towards the second base;
the at least one engagement cavity being positioned offset from the first lateral edge by a first distance;
the at least one engagement cavity being positioned offset from the second lateral edge by a second distance;
wherein the second distance is greater than the first distance or wherein the first distance is greater than the second distance;
an entire cross-section of the at least one engagement cavity being parallel to the first base and the second base;
the attachment body being centrally positioned around and along the rotation axis;
the attachment body being connected adjacent to the second base;
and the entire cross-section of the at least one engagement cavity being concave along a direction from the first lateral edge to the second lateral edge.

2. The advanced holding apparatus as claimed in claim 1 comprising: the at least one concave engagement cavity being a triangular profile.

3. The advanced holding apparatus as claimed in claim 1 comprising:
the bracing surface comprises a first portion and a second portion;
the first portion being positioned along the first distance;
the second portion being positioned along the second distance;
the first portion being a shape selected from the group consisting of: straight line, concave, and convex; and
the second portion being a shape selected from the group consisting of: straight line, concave, and convex.

4. The advanced holding apparatus as claimed in claim 1 comprising:
the at least one screw bit body comprising a first screw bit body and a second screw bit body;
the attachment body being centrally positioned around and along the rotation axis of the first screw bit body;
the attachment body being connected adjacent to the second base of the first screw bit body;
the second screw bit body being concentrically positioned with the first screw bit body;
the second screw bit body being positioned adjacent to the attachment body, opposite the first screw bit body;
the attachment body being connected adjacent to the second base of the second screw bit body;
the first distance of the first screw bit body being greater than the second distance of the first screw bit body; and
the second distance of the second screw bit body being greater than the first distance of the second screw bit body.

5. The advanced holding apparatus as claimed in claim 1 comprising:
the bracing surface comprising a convex portion and a concave portion;
the convex portion being positioned adjacent to the first base;
the concave portion being positioned adjacent to the convex portion, opposite to the first base; and
the convex portion and the concave portion being oriented along the rotation axis of the at least one screw bit body.

6. The advanced holding apparatus as claimed in claim 1 comprising:
the first base comprising a first base surface;
the first base surface and the bracing surface each being flat; and
the first base surface and the bracing surface being oriented perpendicular to each other.

7. The advanced holding apparatus as claimed in claim 2 , wherein the at least one engagement cavity tapers from the first base to the second base such that the triangular profile adjacent to the first base is larger than the triangular profile adjacent to the second base.

8. The advanced holding apparatus as claimed in claim 1 comprising:
a pin-in security hole;
the pin-in security hole being concentrically positioned with the rotation axis of the at least one screw bit body; and
the pin-in security hole normally extending into the at least one screw bit body from the first base.

9. The advanced holding apparatus as claimed in claim 1 comprising:
an engagement bore; and
the engagement bore extending into the attachment body along the rotation axis, opposite the at least one screw bit body.

10. The advanced holding apparatus as claimed in claim 2 comprising:
the triangular profile comprises a plurality of vertexes and a pair of elongated portions;
the pair of elongated portions being interspersed amongst the plurality of vertexes; and
each of the pair of elongated portions being a shape selected from the group consisting of: straight line, concave, and convex.
