## Abstract

The hex drive screw holder includes a spring-loaded end piece having a slot across which the neck of a screw may slide and of which engages and aligns the screw head against the screwdriver bit. The spring-loaded end piece is supported by opposing arms that attach to a urethane body that abuts a depth stopper, which attaches onto the body of the screwdriver bit. The urethane body has a hexagonally shaped hole through which the screwdriver bit passes through. The spring-loaded end piece only moves a small distance to accommodate the screw head and is composed of a urethane composite along with the urethane body. A spring imposes a biasing force on the urethane body and a pressure loading sleeve secured to the screwdriver bit. The hex drive screw holder supports a screw head against a screwdriver bit during installation into a work surface, and provides a means of ingress and egress of the screw to and from the spring-loaded end piece.

## Claims

### Claim 1

A hex drive screw holder comprising:
a screwdriver bit upon which a pressure loading sleeve is secured thereon;
a spring is located between the pressure loading sleeve and a urethane body;
wherein a depth stopper is secured on the screwdriver bit so as to sandwich the urethane body and the spring between the depth stopper and the pressure loading sleeve;
wherein opposing arms extend from the urethane body and support a spring-loaded end piece thereon;
wherein the spring-loaded end piece includes a slot that enables a screw to slide therein so as to align a head of said screw adjacent a bit of the screwdriver bit;
wherein the spring places a biasing force against the urethane body, which is pushed against the depth stopper, whereby producing a clearance between an end of the screwdriver bit and the spring-loaded end piece, which is needed to ensure that the appropriate amount of biasing force is placed from the screwdriver bit onto the head of the screw.

### Claim 2 (depends on 1)

The hex drive screw holder as described in claim 1 wherein the pressure loading sleeve is a collar-shaped object, which secures onto the hex screwdriver bit via a set screw.

### Claim 3 (depends on 2)

The hex drive screw holder as described in claim 2 wherein the urethane body has a hex-shaped hole that enables the screwdriver bit to slide therein.

### Claim 4 (depends on 3)

The hex drive screw holder as described in claim 3 wherein the urethane body has a first side upon which two arm holes are provided so that the opposing arms attach.

### Claim 5 (depends on 4)

The hex drive screw holder as described in claim 4 wherein the depth stopper is a collar-shaped object that slides onto the screwdriver bit and includes a second set screw, which secures the depth stopper onto the screwdriver bit.

### Claim 6 (depends on 5)

The hex drive screw holder as described in claim 5 wherein the depth stopper includes grooves on opposing sides, which accommodate the opposing arms that attach to the urethane body adjacent thereto.

### Claim 7 (depends on 6)

The hex drive screw holder as described in claim 6 wherein the spring-loaded end piece includes a concave notch, which supports a head of the screw.

### Claim 8 (depends on 1)

The hex drive screw holder as described in claim 1 wherein the opposing arms include a first end, a middle portion, and a second end.

### Claim 9 (depends on 8)

The hex drive screw holder as described in claim 8 wherein the first end and the second end have the same diameter, which is less than the diameter of the middle portion.

### Claim 10 (depends on 9)

The hex drive screw holder as described in claim 9 wherein the first end is defined by a distance, which is less than a distance of the middle portion; whereas the second end has a distance that is less than the distance.

### Claim 11 (depends on 1)

The hex drive screw holder as described in claim 1 wherein the screwdriver bit is inserted into a chuck of a drill, and used to drive the screw into a work surface; wherein the spring-loaded end piece supports the screw, and the head of the screw against the bit of the screwdriver bit during use with the drill.

### Claim 12 (depends on 1)

The hex drive screw holder as described in claim 1 wherein the spring-loaded end piece is further defined by a hinge pin transfixed between a first body and a second body; wherein the slot is defined between the first body and the second body; wherein the hinge pin provides a predefined amount of rotational movement of the first body with respect to the second body thereby enlarging the slot formed there between.

### Claim 13

A hex drive screw holder comprising:
a screwdriver bit upon which a pressure loading sleeve is secured thereon;
a spring is located between the pressure loading sleeve and a urethane body;
wherein a depth stopper is secured on the screwdriver bit so as to sandwich the urethane body and the spring between the depth stopper and the pressure loading sleeve;
wherein opposing arms extend from the urethane body and support a spring-loaded end piece thereon;
wherein the spring-loaded end piece includes a slot that enables a screw to slide therein so as to align a head of said screw adjacent a bit of the screwdriver bit;
wherein the spring places a biasing force against the urethane body, which is pushed against the depth stopper, whereby producing a clearance between an end of the screwdriver bit and the spring-loaded end piece, which is needed to ensure that the appropriate amount of biasing force is placed from the screwdriver bit onto the head of the screw;
wherein the screwdriver bit is inserted into a chuck of a drill, and used to drive the screw into a work surface; wherein the spring-loaded end piece supports the screw, and the head of the screw against the bit of the screwdriver bit during use with the drill.

### Claim 14 (depends on 13)

The hex drive screw holder as described in claim 13 wherein the pressure loading sleeve is a collar-shaped object, which secures onto the hex screwdriver bit via a set screw; wherein the urethane body has a hex-shaped hole that enables the screwdriver bit to slide therein.

### Claim 15 (depends on 14)

The hex drive screw holder as described in claim 14 wherein the urethane body has a first side upon which two arm holes are provided so that the opposing arms attach; wherein the depth stopper is a collar-shaped object that slides onto the screwdriver bit and includes a second set screw, which secures the depth stopper onto the screwdriver bit.

### Claim 16 (depends on 15)

The hex drive screw holder as described in claim 15 wherein the depth stopper includes grooves on opposing sides, which accommodate the opposing arms that attach to the urethane body adjacent thereto.

### Claim 17 (depends on 16)

The hex drive screw holder as described in claim 16 wherein the spring-loaded end piece includes a concave notch, which supports a head of the screw.

### Claim 18 (depends on 13)

The hex drive screw holder as described in claim 13 wherein the opposing arms include a first end, a middle portion, and a second end; wherein the first end and the second end have the same diameter, which is less than the diameter of the middle portion; wherein the first end is defined by a distance, which is less than a distance of the middle portion; whereas the second end has a distance that is less than the distance.

### Claim 19 (depends on 13)

The hex drive screw holder as described in claim 13 wherein the spring-loaded end piece may be made of a urethane that provides flexibility to enable the screw to slide in and out of the spring-loaded end piece via the slot.

### Claim 20 (depends on 13)

The hex drive screw holder as described in claim 13 wherein the spring-loaded end piece is further defined by a hinge pin transfixed between a first body and a second body; wherein the slot is defined between the first body and the second body; wherein the hinge pin provides a predefined amount of rotational movement of the first body with respect to the second body thereby enlarging the slot formed there between.
