I finally discovered someone who can put a control system in my observatory. To get prepared for the big day the work begins, January, I need a fairly large number of nuts.
The contractor suggests that EBay is the place to get them at much lower prices than the big h/w stores. Googling: "stainless steel nuts bolts ebay", gives a ton of distributors. Can someone single out one or so of these that has good prices?
Maybe DigiKey or Grainger have competitive prices.
In the meantime, I'll be looking for local prices in our small town.
