My local mom and pop shop was bought out recently, and finding any kind of “unusual” brass screws has been incredibly hard after that blighted event darkened my flow of work. I never considered a domed and slotted brass screw to be exotic, but there you have it. Not one within 70 miles of me, as far as I can find. These guys always have not only, so to speak, the goods, and those entirely satisfactory, but a fast turnaround time as well. Highly recommend whatever they offer. God bless you.
