Sorry about the missing set screw. Anytime there is a hardware problem, please feel free to contact us and we’ll certainly help out. I would have sent you a replacement, and still will, if you like (just contact us). Just FYI, the McMaster part number for that shaft collar is on your bill of materials, and McMaster lists the set screw size on their website.
