Recommendation? Chaves 229 pivot hardware?

[NadrojSnevets]

Does anyone know what the Chaves ultramar redencion 229 kickstop uses in the pivot or all of the screws in general? I can’t seem to find any discussion on the barrel size, thread pitch, screw length, head size etc. My pivot kept working loose and like a dummy I used the benchmade torx bits and it’s rounded off the screws. Looking to replace them from a knife making supplier but I need the right info for the right purchase any help would be appreciated. The Ultramar website contact us part is down btw.
