alright, does anybody know where to get titanium screws? also i have 3x8 flat head screw and then a 3x8 flat head self tapping screw..........and what is the difference between those 2? would it be alright to get titanium flat heads through all of those? or is there a difference? because i also looked at the screws and i see know differences what so ever! and this is just baffling me. thank you
