ʻO nā nati kahi mea hoʻopaʻa maʻamau i hoʻohana ʻia no ka hoʻopili ʻana i nā bolts a i ʻole nā wili e lawelawe ma ke ʻano he hana hoʻopaʻa a sila. ʻO ka papa hana o nā nati e pili ana i ka maʻamau o kona maikaʻi a me kāna hana, a kūpono nā māka like ʻole no nā ʻenekinia like ʻole a me nā hiʻohiʻona noi. Ma kēia ʻatikala, e hoʻolauna mākou i ka pae hana o nā nati a me kona koʻikoʻi, a paipai mākou i kekahi mau huahana nati hana kiʻekiʻe no ʻoe.
Nā māka hana onati ua hoʻokumu pinepine ʻia e ka International Organization for Standardization (ISO) a ʻo nā māka maʻamau he 4.8, 8.8, 10.9 a me 12.9. Hōʻike kēia mau helu i ka ikaika tensile liʻiliʻi a me ka ikaika tensile o ka nut. No ka laʻana, he 800 N/mm² ka ikaika tensile o ka papa 8.8 a me ka ikaika tensile o 800 N/mm². ʻO ke kiʻekiʻe o ka papa, ʻoi aku ka maikaʻi o ka ikaika a me ka maikaʻi o ka nut no nā noi i kau ʻia i nā ikaika a me nā koi.
He mea koʻikoʻi ka pae hana o ka nut i ka palekana a me ka hilinaʻi o ka papahana. Ma ke kaomi kiʻekiʻe, ka wela kiʻekiʻe a i ʻole ka haʻalulu haʻahaʻa, hiki ke wehe a haki paha nā hua haʻahaʻa, e alakaʻi ana i ka hemahema o nā mea hana a i ʻole nā pōʻino. No laila, he mea koʻikoʻi ke koho ʻana i ka māka nut kūpono e hōʻoia i ka hana paʻa o ka papahana.
No ka hoʻokō ʻana i nā pono ʻenehana like ʻole, nui nā huahana nut hana kiʻekiʻe i loaʻa i ka mākeke. No ka laʻana, paipai mākou i ka papa 10.9 a i ʻole12.9 hua , nona ka ikaika kiʻekiʻe a me ka lōʻihi a kūpono i nā kaiapuni i hoʻopaʻa ʻia i nā kaomi kiʻekiʻe a me nā mahana. Eia kekahi, aia nā hua i hana ʻia i nā mea kūikawā e like me nā hua kila kila, nā hua keleawe a me nā titanium nuts, ʻo ia ka corrosion a me ka pale wela a kūpono i nā wahi kūikawā a me nā ʻoihana.
I ke koho ʻana i ka nati, ma waho aʻe o ka pae hana, pono e noʻonoʻo ʻia nā mea ʻē aʻe e like me ke ʻano o ka milo, ka nui o ka nut a me ka pau ʻana o ka ʻili. ʻO nā ʻano milo like ʻole nā kaula maʻamau, maikaʻi a me nā ʻanoʻano, pono e koho ʻia e like me nā pono kikoʻī. Pono e hoʻohālikelike ʻia ka nui o ka nut me ka bolt a i ʻole ka wili e hōʻoia i ka paʻa. Hiki i nā lāʻau lapaʻau ke hoʻomaikaʻi i ka pale ʻana i ka corrosion a me ke ʻano o ka nut, e like me ke galvanizing, nickel plating a me ka uhi.
ʻO ka hōʻuluʻulu manaʻo, ʻo ka pae hana o kahi nut he ana koʻikoʻi o kona maikaʻi a me kāna hana, a ʻo ke koho ʻana i ka māka nut kūpono he mea koʻikoʻi ia i ka palekana a me ka hilinaʻi o ka papahana. I ke koho ʻana i ka nati, ma waho aʻe o ka pae hana, pono e noʻonoʻo ʻia nā mea ʻē aʻe, e like me ke ʻano o ka milo, ka nui o ka nut a me ka pau ʻana o ka ʻili. Paipai mākou i ka hoʻohana ʻana i nā nati hana kiʻekiʻe, e like me ka papa 10.9 a i ʻole 12.9 nati, e hōʻoia i ka hana paʻa o kāu papahana. Inā makemake ʻoe i nā huahana nut hana kiʻekiʻe, e ʻoluʻolukāhea iā mā˚oumainfo@aozhanfasteners.com, e hāʻawi mākou iā ʻoe i nā huahana kiʻekiʻe a me nā lawelawe.
