which screw to fix toplight on bimini hardware of Rinker Fiesta Vee 242

FJ96

Hi,

can anybody tell me which type of screw is used to fix the toplight on the bimini hardware on the FV 242 usually? Guess will be the same as on many other (Rinker) boats.

I live in Germany and and we're using metric screws instead of inch. Since there are several types of inch screw threads, maybe anybody has a hint for me.

Thanks and advance!

Cheers
Frank
