In many hardware stores they have the proper bolt in either bright steel or stainless steel, a flathead phillips. The bright steel can rust so perhaps the stainless might be better. If you want a blued screw you will have to order one special and pay the high extra shipping, many of us dislike that as much as you do. Best of luck. Also I suggest you do not try to get a perfect match between the stock and the reciever until you get quite a bit of expierence with stock work, it is VERY easy to remove too much wood and ruin the stock. Start be taking off about half whatever the extra amount of wood is. With the stock mounted securely to the reciever scribe around the stock with a sharp pointed tool of some sort, similar to an ice pick, then remove the stock and remove the extra wood, ONLY to the line, not INTO the line, but only up to the line. Remount and check, once you get close, STOP for now. It will be better than a factory fit and a great way to start. Go SLOW, take off little amounts at a time, and enjoy it....<><....
