Hoʻohana nui ʻia nā kaula trapezoidal i ka lawe ʻana (feed and lift) a me nā mea hoʻoponopono hoʻonohonoho, a hoʻohana nui ʻia i ka ʻoihana mīkini. ʻO ka ʻae ʻana o nā kaula trapezoidal metric no nā kumu maʻamau e ʻae i ka ʻōnaehana hoʻomanawanui o nā metric maʻamau, a ʻaʻohe waiwai hoʻomanawanui kaʻawale no kēlā me kēia ʻāpana e like me ke kaula alakaʻi (pitch) a me ke kihi sub-ana. No laila, ʻaʻole kūpono kēia thread trapezoidal no nā kaula hoʻouna pololei i loaʻa nā koi kiʻekiʻe no ka hoʻouna pololei ʻana.

Ma muli o ka nui o nā kuhi hewa, kekahi mau pilikia a me nā koi waiwai ma ke kahua o ka ʻike ʻana i ke kaula, ua lawe mai ia i ka pilikia nui i ka ʻae ʻana i nā huahana thread a kanu i nā pōʻino huna he nui i ka maikaʻi o nā huahana mechanical. I mea e hoʻololi maoli i kēia kūlana passive, ua hana ʻo ʻAmelika i ka nui o ka noiʻi ʻenehana no ka ʻike ʻana i ke kaula, a ua manaʻo ʻia ka maʻamau o ka ʻōnaehana hoʻopaʻa ʻana i ke kaula (ASME standard) a me ka ʻike maopopo ʻole o 60º ke ana ʻana i ke ana (ASME technical report). Ke alakaʻi nei ʻo ʻAmelika Hui Pū ʻIa i ka honua i ka hana ʻenehana a me ka ʻenehana hoʻāʻo.

Mai ka ʻōnaehana nānā ʻana i ke kaula o ʻAmelika, hiki iā ʻoe ke aʻo i kekahi ʻenehana hoʻoponopono thread holomua ma ʻAmelika Hui Pū ʻIa. No ka laʻana, hiki i ka hoʻohana ʻana i ka ʻenehana ʻike hōʻike ʻokoʻa ke hoʻomaikaʻi i ka pololei o ka hoʻoponopono ʻana i nā mea mīkini a me nā mea ʻoki ʻoki, a me ka hana ʻana i nā kaula kokoke i ka nui o ka manaʻo.
