I recently purchased a GetRexd tornado rack and am attaching a few additional things to the rack. I’m trying to find matching M24 black zinc hardware (1” bolts, washers, nuts) and cannot seem to find any. Big box hardware stores definitely do not carry (at least mine don’t). Any advice would be appreciated! And yes, I did reach out to GetRxd and they told me to check specialty hardware stores…
