Hexagon bolts pili maoli i nā mea hoʻopaʻa me ke poʻo me ka wili.Hoʻokaʻawale nui ʻia nā bolts i nā bolts hao a me nā bolts stainless steel e like me ka mea.Hoʻokaʻawale ʻia ka hao i nā māka, me nā māka maʻamau ʻo 4.8, 8.8, a me 12.9.Hana ʻia ke kila kila me ke kila kila SUS201, SUS304, a me SUS316 bolts.
ʻO kahi pūʻulu piha o nā bolts hexagon he poʻo bolt, kahi nut, a me kahi gasket flat
Hexagonal bolts head bolts hexagonal head bolts (partial threads) – c hexagonal head bolts (full threads) – c grade, also known as hexagonal head bolts (rough) hexagonal head bolts, black iron screws.ʻO nā kūlana maʻamau i hoʻohana nui ʻia: sh3404, hg20613, hg20634, etc.
ʻO ke poʻo hexagon bolt (i hoʻopau ʻia he hexagon bolt) he poʻo a me ke koʻokoʻo wili (
Hoʻokaʻawale ʻia nā māka hana piha o nā bolts no ka hoʻopili ʻana i nā hale kila i ʻoi aku ma mua o 10 mau māka, me 3.6, 4.6, 4.8, 5.6, 6.8, 8.8, 9.8, 10.9, a me 12.9.Ma waena o lākou, ʻo nā bolts o ka papa 8.8 a i luna, i hana ʻia me ke kila haʻahaʻa haʻahaʻa a i ʻole ke kila kalapona maʻamau a loaʻa i ka mālama wela kūpono (quenching and tempering), i kapa ʻia ʻo nā bolts ikaika kiʻekiʻe, aʻo ke koena e kuhikuhi pinepine ʻia. e like me nā kī maʻamau.ʻElua ʻāpana o nā helu e hōʻike ana i ka waiwai ikaika tensile nominal a me ka ratio hua o ka mea bolt.Eia kekahi laʻana.
ʻO ke ʻano o nā bolts me ka pae hana o 4.6 ʻo ia:
ʻO ka ikaika tensile nominal o ka mea bolt hiki i 400 mpa;
2. ʻO ka lākiō ikaika o nā mea bolt he 0.6;
3. Nominal yield ikaika o bolt mea a hiki i 400 × 0.6=240MPa pae
ʻO nā bolts ikaika kiʻekiʻe me ka helu hana o 10.9, a hiki i ka mea ma hope o ka mālama wela:
1. ʻO ka ikaika tensile nominal o ka mea bolt hiki i 1000MPa;
2. ʻO ka lākiō ikaika o nā mea bolt he 0.9;
ʻO ka ikaika hāʻawi inoa o nā mea bolt hiki i 1000 × 0.9 = 900MPa pae
ʻO ke ʻano o nā māka like ʻole o ka hana bolt he maʻamau i ʻae ʻia ma ka honua.Loaʻa ka hana like ʻana o nā bolt me ​​ka papa loiloi hana like ʻole me ka nānā ʻole i kā lākou mea a me ke kumu, a hiki ke koho ʻia ka papa kuhikuhi hana palekana no ka hoʻolālā ʻana.
