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. ## Claims ### Claim 1 A captive locating screw assembly comprising: a shaft comprising a threaded portion and an opposing attaching portion, and having a body extending therebetween, said attaching portion having an attaching bore; a handle having a sleeve portion, said sleeve portion having a radial bore and a ventral bore; and a fastener; 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. ### Claim 2 (depends on 1) The assembly of claim 1, wherein said body is generally smooth and has a radius larger than the radius of said attaching portion. ### Claim 3 (depends on 1) The assembly of claim 1, wherein the threads of said threaded portion have a radius about the same as the radius of said body. ### Claim 4 (depends on 1) The assembly of claim 1, wherein the threads of said threaded portion have a radius greater than the radius of said attaching portion. ### Claim 5 (depends on 1) The assembly of claim 1, wherein the central axis of said attaching bore is generally perpendicular to the central axis of said shaft. ### Claim 6 (depends on 1) The assembly of claim 1, wherein the central axis of said attaching bore intersects the central axis of said shaft. ### Claim 7 (depends on 1) The assembly of claim 1, where said handle comprises a central body having a plurality of protrusions attached to a periphery thereof. ### Claim 8 (depends on 1) The assembly of claim 1, wherein said protrusions are configured for twisting by a human hand. ### Claim 9 (depends on 1) The assembly of claim 1, wherein said handle and said sleeve portion are generally coaxial. ### Claim 10 (depends on 1) The assembly of claim 1, wherein said radial bore is generally parallel to said attaching bore. ### Claim 11 (depends on 1) The assembly of claim 1, wherein said radial bore intersects said ventral bore. ### Claim 12 (depends on 1) The assembly of claim 1, wherein said radial bore is generally perpendicular to said ventral bore. ### Claim 13 (depends on 1) The assembly of claim 1, wherein said fastener is a roll pin. ### Claim 14 (depends on 1) The assembly of claim 1, further comprising a washer having an axial washer bore, said washer bore sized and shaped for said attaching portion to be inserted therethrough. ### Claim 15 (depends on 14) The assembly of claim 14, wherein said attaching portion is inserted through said washer bore and 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 to fasten said shaft to said handle, and said washer is held between said sleeve portion and said body portion. ### Claim 16 (depends on 15) The assembly of claim 15, wherein said washer spins independently of said shaft and said handle. ### Claim 17 (depends on 1) The assembly of claim 1 in a captive locating screw system further comprising a bushing assembly configured to accept said captive locating screw assembly. ### Claim 18 (depends on 17) The system of claim 17, wherein said bushing assembly further comprises a locking means. ### Claim 19 (depends on 18) The system of claim 18, wherein said captive locating screw assembly is locked to said bushing assembly with said locking means. ### Claim 20 A method for holding a work piece comprising: providing a work surface having at least one threaded receiving bore; providing a work piece having at least one through bore; providing a captive locating screw assembly comprising: a shaft comprising a threaded portion and an opposing attaching portion, and having a body extending therebetween, said attaching portion having an attaching bore; a handle having a sleeve portion, said sleeve portion having a radial bore and a ventral bore; providing a bushing assembly configured to accept said captive locating screw assembly, said bushing assembly having a locking means; assembling said captive locating screw assembly by: inserting said attaching portion into said ventral bore such that said attaching bore and said radial bore are generally linearly aligned; and inserting said fastener through said attaching bore and said radial bore to fastens said shaft to said handle; aligning axially said through bore and said receiving bore; seating said bushing assembly in said through bore; using said gripping means, screwing said assembled captive locating screw assembly into said receiving bore through said bushing assembly in said through bore; and locking said captive locating screw assembly to said bushing assembly with said locking means.
