M1B Screws and Plastic Films

Hi everyone,

I have a question about how to tighten M1B screws.

Screw holes of M1B that are on M1 board have yellow plastic films.
Did you remove these films before tighten screws?
Or did you tighten screws breaking films?

Best Regards,

Hi there!

I think the orange plastic films are just there to protect the threading from dust. It must be removed before the screws go in. Machine screws match very closely to the threading and the films are too thick and rigid as a padding material.
