Common or ‘Slotted Oval Head screws are difficult to find especially in Black, used in many applications in bygone years, Blacksmith Bolt to the rescue !

#8 X 1-1/4" SOH Wood Screws, Black Oxide

Period correct screws used in the building and repair of black powder muzzleloaders and my son uses in his repairing of firearms in his gunsmithing business.

Great quality worked out well

I was doing some cosmetic restoration on an 1885 pump organ, but many of the screws were missing. These look exactly like the originals. So glad I found them.
