I went to the store to get some longer screws for my lowrider rack because the ones that came with the rack are too small for the thread in the fork and the ones on the bike aren't long enough since the rack is probably made for newer/larger touring forks and I have no place for spacers with the short screws. I came to a conclusion that the screws seems to be sized 1/4 x 32 and I want them in 1 1/2 lenght. All the 1/4 screws I find are 20 tpi threaded, I can't find 32 tpi threads. Is there a metric equivalent I should look for? The #10's are too small, they only fit in the lower brazon.
My bike is a 1990 Miyata 1000LT if it helps.
