there is a place somehwere in the threads were you can order extra screws i did and ordered 10 so i have extra screws because when i went on vacation last year to florida i was on the star tours ride and the screww loosen ed up and i lost it on the ride , so i made sure now that before i go out with my bag i make sure the screw is as tight as can be-------------------and if you need to have it replaced todds will send you and extra one if you need it cause i sent him a note when i lost mine and he sent it and then i found the site to order the screws from , i'll search around here or on cow to see if the chicago screws site is there .
