Dog nuts missing on multi purpose table

One dog was missing the nut for the tightening screw. Looks like someone ground down a hex nut to make it fit the channel in the dog; can we buy some additional replacements? Could not find any in the box with dogs and accessories.

I bought some t nuts recently we should have extras somewhere.

This is the second time these nuts have been lost - please do not disassemble these (???)
