A #6 screw, nut and washers were used in conjunction with the dimple dies that have the holes in them to form the dimples. However, it first required a considerable amount of filing to custom fit the #6 screw to the dies. The tops of the threads on the screw required gentle filing with a diamond file … but just enough so the screw could barely slip into the dimple dies, this took a little time to get it right.
