Looking to do the 3 in 1 charcoal grate mod an not a welder so went to find the u bolts at acehardware shown in the mod section. They had a large selection of them but they are all zinc plated. I can't tell from the pictures on the mod but it appears o be really shiny and I assume it is zinc posed as well. Is this safe to do or will I get sick from the fumes or taint the food?
