US 8,539,865 B1 · Hex drive screw holder

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.

Dependent claims

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.
