	I need a new screw that goes through the front mount of my STS scope, somehow the original has got bent and won't turn smoothly. Finding something here that does not have a Phillips head and is blued, is nigh on impossible. Mike.

	The real issue will be getting the old one out. I once agreed to try. Was successful but it took a lot of work to figure out WHERE? the Screw was, and how to make a setup that would put me right on it. Then drilled a series of holes from way under size thru the screw and opening it up with a left hand twist drill when it got near minor diameter. And then it just grabbed and screwed itself right out of the Aluminum. Also I got a replacement from the guy in Texas I think that just went in nice. The best advice you can give to a new shooter is 'DO NOT USE A SCREW DRIVER ON THESE, THEY ARE DAMAGED EASILY" Use either a Penny or a Quarter finger tight. FITZ. OLD TUCK. P.S. My memory seems to be telling me these were a fine thread, either forty or forty eight pitch cannot remember right now but Taps were available. FITZ.

	Sorry if I have caused some confusion but the screw I need is the one that passes through the serrated thumb wheel in the front mount. I don't know what that wheel is called as I don't have a parts list. Mike. PS Where might one obtain a parts list in case I encounter more problems at a later date ?.

	Can anyone with a parts diagram or part number help, are there any parts suppliers in your neck of the woods, there's none here. Mike.

	This is Unertl's dehorned mount but the screw should be the similar. I believe you are looking for item 16. Hope it helps. (You need to *Login* or *Register* to view media files and links)

	Here is a patent on these type mounts which shows a pin retaining the screw. (You need to *Login* or *Register* to view media files and links)

	Mick B The place to get a replacement clamp screw for your STS is Parson's Scope Service. He has helped me on a number of STS scope repairs beltfed/arnie

	Kurt Thanks for the drawings, now I have an idea of the part number although I'm still a little confused, the first drawing shows the screw as part # 16 and the wheel it passes through as part # 15. The second drawing shows what appears to be the same bits, but this time the screw part number 8 and the wheel is part # 9. Anyway I will now contact Parsons and see if they have one in stock, it may pay to get a couple so I have a spare. Thanks to both you and Arnie for all your help. Mike.

	The first drawling is of a Unertl dehorned mount. I could not find the patent for Unertl Target mount. The second drawling is from someone else patent. I think it is the same as Fecker. D.A. Baker worked for Fecker.

	Kurt I have sent an enquiry to Parsons giving them the part numbers from the drawings you posted, I didn't notice they were Unertl scopes, hope they can sort my problem and I have not confused them with the part numbers. Mike.
