1. A captive locating screw assembly comprising:
- a shaft generally in the configuration of an elongated cylinder, said shaft comprising;
a threaded portion disposed at a first end of said shaft;
an attaching portion disposed at a second end of said shaft opposing said first end, said attaching portion having an attaching bore radially disposed therein;
a body portion extending between said threaded portion and said attaching portion;
a handle configured to be twisted by a human hand, said handle having attached thereto a sleeve portion generally in the configuration of a cylinder, said sleeve portion having a radial bore radially disposed therein and a ventral bore ventrally disposed therein; and
a fastener;
wherein said attaching bore and said radial bore are configured such that, when said attaching portion is inserted into said ventral bore, said shaft may be rotated to align said attaching bore and said radial bore generally linearly; and
wherein said attaching portion is inserted into said ventral bore such that said attaching bore and said radial bore are generally linearly aligned, and said fastener is inserted through said attaching bore and said radial bore and fastens said shaft to said handle.

Abstract
A captive locating screw system comprising a captive locating screw assembly configured for use with a bushing assembly. The captive locating screw assembly has a gripping means attachable to be threaded shaft or stud and an optional protecting means disposed between the gripping means and the body of the shaft. The protecting means may be a washer or other similar structure, and remains statically in contact with a workpiece or work surface, to reduce damage or marring, even as the captive locating screw assembly is rotated by twisting the gripping means to fasten it to the workpiece or work surface.
