Esslinger, Ofrei and a few.others. Just be glad it was not an H-screw.
Ive seen the H screws for sale on aliexpress if your looking for some
I think that is where I got.mine. But I had to buy 100 screws. Thank goodness they were a mix assortment. Other places.had them at 7 bucks for one or.two.screws.
Oh, i did a search and didnt find anything. I even asked Tompa who had the same problem. Anyway, thank you, i will search again
