US 2008/0289459 A1 · Screw Holding and Driving-Control Apparatus and Method

Abstract

An improved screw holding and driving device that enables the user to control the screw depth for use with power drills/drivers. The tool has a screw holding/driving device with an optional inset magnet mating with a standard screw driving bit or screw and a sliding outer sleeve with a depth-controlling flared head to absorb and distribute driving force and a depth control depth control stop at a selected longitudinal position based on the controlled depth to which it is desired to drive the screw. The sleeve is cable of complete free rotation and the depth control nut and retaining ring allow the user to set the depth to allow minimal surface penetration/dimpling for materials like drywall board or set above the material for fine carpentry to allow hand driving to complete screw attachment.

Dependent claims

An apparatus for driving a screw to a controlled depth while simultaneously stabilizing the screw during the driving, comprising:

a screw control sleeve for stabilizing the screw while the screw is being driven;
a screw driving device situated longitudinally and slidably within said screw control sleeve, configured to mate proximate a forward end thereof with a standard screw driver bit for driving the screw or directly with the screw, and configured to be rotationally driven proximate a rearward end thereof by a rotational driving device;
and
a depth control stop adjustably fixed by the user at a selected longitudinal position of said screw driving device based on the controlled depth to which a user of said apparatus desires to drive the screw;
wherein:
when said screw driving device is driven forward by the rotational driving device, a portion of said depth control stop comes to butt against a portion of said screw control sleeve, such that said screw driving device cannot be driven forward any further and hence the screw cannot be driven forward any further.
