Cried in Japan when a double aught-256 piece of hardware disappeared. Here in the States, we stock both kinds of hardware, metric and SAE. Supply companies really love this as it represents double overhead. > My problem is that 6mm bolts look under-sized when compared to 1/4-20 :-) --~--~---------~--~----~------------~-------~--~----~ NavList message boards: www.fer3.com/arc Or post by email to: NavList@fer3.com To , email NavList+@fer3.com -~----------~----~----~----~------~----~------~--~---
