In need of scope base screws...thread pitch...I have a one piece scope base for a savage 10..round receiver. The front screws were stripped when they were removed. I purchased in grab box at gun show. They have Torx head. and are recessed in mount. I only need thread pitch for the screws that go into the action and I can purchase screws from Brownells..I think I could buy ones a little longer and cut down. Any help appreciated.
