Thanks for the lead
But the Store told me they don't have what are called sex bolts....ya that's what they are called. They told me that McMaster-Carr might be a good place to look and they will sell you as many as you need and not a bag of 25. Still looking....is there a way of contacting the company to see if they have the bolts? T
