Ua ʻae ʻia i ka makahiki 1936, ua hoʻohana nui ʻia kēia kikoʻī i ka ʻaila a me nā noi hana kemika. Hoʻopili ka maʻamau ASTM i ke kila kila a me nā mea bolting kila kila no ka lawelawe wela kiʻekiʻe. Aia kēia kikoʻī i nā mea hoʻopaʻa i manaʻo ʻia no ka hoʻohana ʻana i nā ipu kaomi, nā valve, nā flanges, a me nā mea pono. ʻOiai, loaʻa pinepine ʻia kēia mea i loko o nā pitch thread coarse national (UNC), inā hoʻohana ʻia i nā noi kuʻuna, ua kuhikuhi ʻia nā milo he 8 ʻīniha no ka ʻīniha (tpi) no nā anawaena ma luna o hoʻokahi ʻīniha.
Aia ma lalo kahi hōʻuluʻulu kumu o kekahi o nā māka maʻamau. Uhi ʻo ASTM A193 i kekahi mau kikoʻī maʻamau ʻaʻole i uhi ʻia i kēia wehewehe me B5, B6, a me B16.
