Pono kekahi mau kikoʻī ASTM i ke poʻo hex ʻoi aku ka nui ma mua o ke poʻo hex maʻamau (hoʻopau).Aia kēia mau kikoʻī: A193, A320 a me A307B.ʻOiai ʻo A325 a me A490 bolts e koi pū i ke poʻo hex kaumaha, e ʻoluʻolu e nānā i Structural Bolts no nā kikoʻī kikoʻī, no ka mea, ʻoi aku ka pōkole o kēia mau bolts ma mua o nā bolts hex kaumaha maʻamau.
Kaumaha Hex Bolts Noi
Hiki ke hoʻohana ʻia nā bolts hex kaumaha no nā noi like ʻole e pili ana i ka hoʻopaʻa ʻana i ka lāʻau, ke kila, a me nā mea hana ʻē aʻe no nā papahana e like me nā pahu, nā alahaka, nā hale alanui, a me nā hale.Hoʻohana mau ʻia nā pōkā hex kaumaha me nā poʻo i hoʻopaʻa ʻia e like me nā kī heleuma poʻo.
ʻO nā bolts hex structural bolts he kumu nui ia o ka handan haosheng bolts range, ʻoi aku ka astm a325, a490, DIN6914 i makemake nui ʻia a hoʻohana ʻia i nā hana kūkulu e like me ka tunnel a me ke alahaka, ke alahao, ka aila a me ke kinoea, a me ka ʻoihana ikehu makani.
ʻO ke kila kila
ʻO ka pahu kila kahi ʻano o ka ikaika kiʻekiʻe, a me ke ʻano o nā ʻāpana maʻamau.ʻOi aku ka maikaʻi o ka hana hoʻopaʻa ʻana, hoʻohana ʻia no ka hoʻolālā kila, ʻenekinia, no laila ka hopena paʻa.Ma ka hale kila maʻamau, koi ʻia nā bolts kūkulu kila ma luna o ka papa 8.8, a me ka papa 10.9 a me ka papa 12.9, ʻo ia mau mea āpau he mau kī kila ikaika kiʻekiʻe.
Hoʻokaʻawale ʻia ka pahu kila i ke ʻano torsional shear type kiʻekiʻe ka ikaika a me ka hexagonal nui ka ikaika kiʻekiʻe, ka hexagonal nui ka ikaika kiʻekiʻe o ka ikaika kiʻekiʻe o ka wili maʻamau, a ʻo ka torsional shear ʻano kiʻekiʻe ka hoʻomaikaʻi ʻana i ka nui. hexagonal kiʻekiʻe-ikaika bolt, i mea e oi aku ka hana.
Pono e hoʻopaʻa mua ʻia ke kūkulu ʻia ʻana o nā bolts hale kila a laila hoʻopaʻa ʻia, a pono e hoʻohana nā bolts hale kila e hoʻohana i ke ʻano hopena uila a i ʻole torque adjustable wrench uila;A he koi koʻikoʻi ko ka hope hoʻopaʻa ʻana i ke kila, ʻo ka hoʻopaʻa hope ʻana i ka torsion shear steel structure bolts e hoʻohana i ka torsional shear type wrench uwila, ʻo ka hoʻopaʻa hope ʻana i ka torque steel structure bolts e hoʻohana i ka torsional type uila.
ʻO ka bolt structural hexagon nui he hoʻokahi bolt, hoʻokahi nut, a me ʻelua mea holoi.
ʻO nā kī hexagon nui no ka hana kila.
ʻO ka pahu kila shear torsional he pahu, ka nut a me ka mea holoi.
