Kei roto i tenei whakakitenga nga toronga mo te whakamahi i roto i nga oko pehanga, i nga maru, i nga kopa me nga taputapu. Ahakoa, he maha nga wa e waatea ana tenei rauemi i roto i nga papa miro taratara o te motu (UNC), mena ka whakamahia i roto i nga tono tuku iho, ka tohua nga miro kia 8 nga miro mo ia inihi (tpi) mo nga diameter i runga ake i te kotahi inihi.

    Kei raro nei he whakarāpopototanga taketake o etahi o nga reanga noa. Kei te hipoki te ASTM A193 i te maha atu o nga whakaritenga paerewa karekau i roto i tenei whakaahuatanga tae atu ki te B5, B6, me B16.
