Answered: Nylon Patch on Screws

My team and I have a lot of screws that don’t have nylon locking patches on them. We think we are allowed to put a patch on them ourselves because they would be functionally identical to screws that vex offers. Our question is, can we put the patch on shoulder screws?

Yes, as per <R15b>, this is legal. Please see below for the exact wording of the rule.
