Fabbed up and welded a cap on that corner. Looks really good. Called all over including Mark's nuts and bolts, copper state, Phoenix nuts and bolts, McMaster car, etc. Looks like those hex head Allen screws are a unicorn. I have 180 on order and we'll take two weeks to get here. Although this first of three sections I just finished the trim on has 75 screws by itself. So I will need to order some more.those little suckers are expensive.$80 for the first order that is coming. I think the blackhead with a larger screw head will pop nicely against the bronze painted trim.
