## Abstract

A secondary screw that is used to penetrate through a conventional threaded screw. The secondary screw is inserted into a conventional screw that might be mounted or inserted into a wall or a post. The secondary screw provides a means to avoid leaving a hole in a wall or post by removing the primary threaded screw. In one particular embodiment, a primary screw is inserted into a wall, then the secondary screw screws into the top head of the primary screw. This arrangement enables a user to use the secondary screw as a means to hang any object upon the screw or mount any object through the use of the secondary screw.

## Claims

### Claim 1

A dual screw configuration comprising:
a. a primary screw, where the primary screw includes a head and a stem, further where stem includes self taping threads; and
b. a secondary screw, where the secondary screw includes a head and a stem, where the stem of the secondary screw inserts into the head of the primary screw.

### Claim 2 (depends on 1)

The dual screw configuration according to claim 1, where the secondary screw is for temporary usage and is removable after use.

### Claim 3 (depends on 2)

The dual screw configuration according to claim 2, where the primary screw remains in the wall permanently after removal of the secondary screw.

### Claim 4

A method of screw reinforcement comprising the steps of:
a. inserting a first screw into a wall, where the first screw includes self taping threads;
b. inserting a second screw into an opening provided in the first screw;
c. driving the second screw into the opening along the length of the first screw to reinforce the strength of the first screw;
d. removing the second screw after usage of the second screw; and
e. driving the first screw flush into the wall after completion of use the first screw.
