Abstract

A screw bit body allowing for torque force application onto a socket fastener. The screw bit body includes a plurality of laterally-bracing sidewalls, a plurality of intermittent sidewalls, a first base, and a second base. The laterally-bracing sidewalls and plurality of intermittent 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 a gripping point to prevent slippage in between the screw bit body and the socket fastener. The engagement cavity traverses normal and into the concave surface and the convex surface. The engagement cavity includes an angled driving portion and a concave portion. The angled driving portion is positioned adjacent to the first lateral edge with the concave portion being positioned opposite to the first lateral edge, across the angled driving portion.

First claim

What is claimed is:

1. A multi-directional driver bit comprising:
at least one screw bit body;
the screw bit body comprising a plurality of laterally-bracing sidewalls, a plurality of intermittent 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 an engagement cavity, the first lateral edge and the second lateral edge being positioned opposite to each other across the bracing surface, the engagement cavity traversing normal and into the bracing surface, the engagement cavity traversing into the at least one screw bit body from the first base towards the second base, the engagement cavity comprising an angled driving portion and a concave portion, the angled driving portion being positioned adjacent to the first lateral edge, the angled driving portion being positioned in between the first lateral edge and the concave portion, a first end of the angled driving portion being positioned coincident with the first lateral edge, a second end of the angled driving portion being positioned adjacent to the concave portion, the bracing surface being flat, the angled driving portion being flat;
the bracing surface being colinear with the first lateral edge and the second lateral edge;
the angled driving portion being not coplanar with the bracing surface for each of the plurality of laterally-bracing sidewalls;
the plurality of laterally-bracing sidewalls being radially positioned about a rotation axis of the at least one screw bit body;
the plurality of intermittent sidewalls being radially positioned about the rotation axis of the at least one screw bit body;
the plurality of intermittent sidewalls being flat;
the plurality of intermittent sidewalls being interspersed among the plurality of laterally-bracing sidewalls; and
the bracing surface of an arbitrary laterally-bracing sidewall among the plurality of laterally-bracing sidewalls being angularly offset from an adjacent intermittent sidewall among the plurality of intermittent sidewalls by an obtuse angle so as to create a gripping tooth.

2. The multi-directional driver bit as claimed in claim 1 comprises:
an attachment body;
an engagement bore;
the attachment body being centrally positioned around and along the rotation axis;
the attachment body being connected adjacent to the second base; and
the engagement bore traversing into the attachment body along the rotation axis, opposite the screw bit body.

3. The multi-directional driver bit as claimed in claim 1 comprises:
an attachment body;
the attachment body being centrally positioned around and along the rotation axis; and
the attachment body being connected adjacent to the second base.

4. The multi-directional driver bit as claimed in claim 1 , wherein the plurality of intermittent sidewalls and the plurality of laterally-bracing sidewalls radially alternate between each other about the rotation axis of the screw bit body.

5. The multi-directional driver bit as claimed in claim 1 , wherein the first lateral edge, the second lateral edge, and the bracing surface taper from the first base to the second base.

6. The multi-directional driver bit as claimed in claim 1 , wherein the engagement cavity tapers from the first base to the second base.

7. The multi-directional driver bit as claimed in claim 1 , wherein a driving width distance of the angled driving portion perpendicular to the rotation axis is tapered from the from the second base to the first base.

8. The multi-directional driver bit as claimed in claim 1 , wherein a bracing width distance of the bracing surface perpendicular to the rotation axis is tapered from the from the second base to the first base.

9. The multi-directional driver bit as claimed in claim 1 , further comprising:
the concave portion comprising a plurality of planar portions; and
each of the plurality of planar portions being connected to one another at angles less than 180 degrees.

10. The multi-directional driver bit as claimed in claim 1 , further comprising:
the concave portion comprising at least one curved portion and at least one planar portion; and
each of the at least one curved portion and the at least one planar portion being connected to one another at angles less than 180 degrees.
