I didn’t see replacement screws or washers listed on the website, and unfortunately my customer lost his. Do you have replacements or specs that I can use to purchase them locally?
I don’t think you can order them separate from any vendor. You might try contacting Ping to see if they’ll send you one. Or just run a google search to see if someone has one for sale. I found some on e-bay.
