Nā Kikoʻī Maʻamau no nā wili

ʻO nā kūlana i hoʻohana pinepine ʻia penei:
GB-Kina National Standard (National Standard)
ANSI-ʻAmelika Kūlana Lahui (ʻAmelika Kūlana)
DIN-Kūlana Kūlana Aupuni Kelemania (Kūlana Kūlana Kelemania)
Kūlana ASME-ʻAhahui ʻAmelika o nā ʻenekinia mīkini
JIS-Ke Kūlana Lahui Kepanī (Ke Kūlana Kepanī)
BSW-Pelekania Lahui Kūlana

Ma waho aʻe o kekahi mau ana kumu, e like me ka mānoanoa o ke poʻo a me ke poʻo ma ka ʻaoʻao ʻē aʻe, ʻo ka ʻāpana ʻokoʻa loa o nā kūlana i ʻōlelo ʻia no nā wili, ʻo ia ke kaula. ʻO nā kaula o GB, DIN, JIS, a me nā mea ʻē aʻe, aia ma MM (milimita), i kapa ʻia he mau kaula metric. ʻO nā kaula e like me ANSI, ASME, aia ma nā ʻīniha a ua kapa ʻia he mau kaula maʻamau ʻAmelika. Ma waho aʻe o nā kaula metric a me nā kaula ʻAmelika, aia kekahi kūlana BSW-British, a aia nā kaula ma nā ʻīniha, i ʻike nui ʻia ʻo nā kaula Whitworth.

ʻO ke kaula metric ma MM (mm), a ʻo kona kihi cusp he 60 degere. Ua ana ʻia nā kaula ʻAmelika a me Imperial ma nā ʻīniha. ʻO ke kihi cusp o ke kaula ʻAmelika he 60 degere hoʻi, ʻoiai ʻo ke kihi cusp o ke kaula Pelekane he 55 degere. Ma muli o nā ʻāpana ana like ʻole, ʻokoʻa hoʻi nā ʻano hōʻike o nā kaula like ʻole. No ka laʻana, hōʻike ʻo M16-2X60 i kahi kaula metric. ʻO ia hoʻi ke anawaena inoa o ka wili he 16MM, ʻo ka pitch he 2MM, a ʻo ka lōʻihi he 60MM. ʻO kekahi laʻana: ʻo 1/4-20X3/4 ke ʻano o ke kaula ʻōnaehana Pelekane. ʻO kona manaʻo kikoʻī ʻo ke anawaena inoa o ka wili he 1/4 ʻīniha (hoʻokahi ʻīniha = 25.4MM), aia he 20 niho ma hoʻokahi ʻīniha, a ʻo ka lōʻihi he 3/4 ʻīniha. Eia kekahi, inā makemake ʻoe e hōʻike i nā wili i hana ʻia e ʻAmelika, hoʻohui pinepine ʻia ʻo UNC a me UNF ma hope o nā wili i hana ʻia e Pelekane e hoʻokaʻawale ma waena o nā kaula coarse i hana ʻia e ʻAmelika a me nā kaula maikaʻi i hana ʻia e ʻAmelika.

ʻO Yihe enterprise kahi ʻoihana i loea i ka hana ʻana i nā wili amchine i hana ʻia ma US ANSI, BS machine screw, bolt corrugated, indlcuidng 2BA, 3BA, 4BA; Nā wili mīkini i hana ʻia ma Kelemania DIN (DIN84/ DIN963/ DIN7985/ DIN966/ DIN964/ DIN967); GB Series a me nā ʻano huahana maʻamau a me nā huahana maʻamau ʻole e like me nā wili mīkini a me nā ʻano wili mīkini keleawe āpau.
