- ISO technical committees for fasteners are divided into two groups: TC1-fastener threads and TC2-fasteners. TC2 is divided into 5 sub-committees, namely TC2/SC7-reference standard, TC2/SC11-metric external thread fastener, TC2/SC12-metric internal thread fastener, TC2/SC13-non-metric thread fastener , as well as TC2/SC14-surface coating. The following are the standards issued by the committees in 2011.
