The one marked A2-70 is stainless steel. https://www.fastenal.com/content/product_specifications/M.SHCS.4762.A2-70.pdf
A regular metric steel socket head cap screw will work, but you risk it rusting if you leave it in for any length of time. So you can use the other one, but replace it soon. I’d check Home Depot. They keep a surprisingly good selection of metric bolts. -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.
