Abstract

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 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. A multi-grip screw 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, at least one flat sidewall, a first base, a second base, and at least one engagement cavity;
the plurality of laterally-bracing sidewalls comprising a first lateral edge, a second lateral edge, and a bracing surface;
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 first lateral edge and the second lateral edge being angular in shape formed by intersecting straight lines;
the at least one engagement cavity extending normal and into the bracing surface of at least one specific sidewall from the plurality of laterally-bracing sidewalls;
the at least one flat sidewall being positioned adjacent to the at least one specific sidewall;
the at least one engagement cavity extending into the at least one screw bit body from the first base towards the second base;
an entire cross-section of the at least one engagement cavity being parallel to the first base and the second base; and
the attachment body being connected adjacent to the second base.

2. The multi-grip screw apparatus as claimed in claim 1 , wherein the at least one screw bit body tapers from the first base to the second base.

3. The multi-grip screw apparatus as claimed in claim 1 , wherein the at least one screw bit body tapers from the second base towards the first base.

4. The multi-grip screw apparatus as claimed in claim 1 comprising:
the at least one engagement cavity being positioned offset from the first lateral edge of the at least one specific sidewall by a first distance;
a first portion of the bracing surface of the at least one specific sidewall being positioned along the first distance; and
the first portion being a shape selected from the group consisting of: straight line, concave, and convex.

5. The multi-grip screw apparatus as claimed in claim 1 comprising:
the at least one engagement cavity being positioned offset from the second lateral edge of the at least one specific sidewall by a second distance;
a second portion of the bracing surface of the at least one specific sidewall being positioned along the second distance; and
the second portion being a shape selected from the group consisting of: straight line, concave, and convex.

6. The multi-grip screw apparatus as claimed in claim 1 comprising:
a second portion of the bracing surface of the at least one specific sidewall being positioned at a portion angle from a first portion of the bracing surface of the at least one specific sidewall.

7. The multi-grip screw apparatus as claimed in claim 1 comprising:
the at least one engagement cavity being positioned offset from the first lateral edge of the at least one specific sidewall by a first distance;
the at least one engagement cavity being positioned offset from the second lateral edge of the at least one specific sidewall by a second distance; and
the first distance being equal to the second distance.

8. The multi-grip screw apparatus as claimed in claim 1 comprising:
the at least one screw bit body further comprising a plurality of intermittent sidewalls;
the plurality of intermittent sidewalls being radially positioned about the rotation axis; and
the plurality of intermittent sidewalls being interspersed amongst the plurality of laterally-bracing sidewalls.

9. The multi-grip screw apparatus as claimed in claim 1 , wherein a lateral edge between the first base and each of the plurality of laterally-bracing sidewalls is chamfered.

10. The multi-grip screw apparatus as claimed in claim 1 , wherein the at least one engagement cavity tapers from the first base to the second base.
