Both of these sites have the M1.7x3 screws. I had to create an account to order, and them come in packs of 50, so with shipping, over $20 from both sites, but they had them. https://www.nbk1560.com/en-US/products/specialscrew/nedzicom/miniat...-M/SNZS-M1.7/ https://us.misumi-ec.com/vona2/detail/110300243810/ Thanks Old Turkey for the size information!
