craftsman827 Report post Posted February 23, 2016 Does anyone know where to purchase LARGE rivets ? When I say large, I mean the diameter of the top part, not the length of the shaft. I've been using flat spots, one piece with prongs, I need something for 9 oz. leather. The photo is of the spots I am using now. The prongs are too short for 9/10 oz. H.O. leather.
