Two Sanwa JLF questions, please help..Mounting screws + does your dust washer clank?

  1. What are the best screws to attach the stick itself to the mounting plate in a Hori RAP 4 Kai? I have it on now but it just seems like the screws are barely making it to the threads and will come out easy.

  2. Do your Sanwa dust washers clank? Like a casino chip? I don’t notice this on any of my other arcade sticks. Here is a video, hopefully you can hear it:

Is the screws cross-threaded?
