He 4 mau kī hexagon i hoʻohana mau ʻia:
1. GB/T 5780-2016 "Hexagon Head Bolts Papa C"
2. GB / T 5781-2016 "Hexagon poʻo bolts me ka piha piha C papa"
3. GB/T 5782-2016 "Hexagon Head Bolts"
4. GB/T 5783-2016 "Hexagon head bolts with full thread"
ʻO nā ʻokoʻa nui ma waena o nā ʻehā i hoʻohana pinepine ʻia e like me kēia:
1. Nā lōʻihi like ʻole:
ʻO ka lōʻihi o ka wili o ka pahu he milo piha a me ke kaula piha ʻole.
Ma waena o nā 4 i hoʻohana mau ʻia i luna
ʻO GB / T 5780-2016 "Hexagon Head Bolts Class C" a me GB / T 5782-2016 "Hexagon Head Bolts" ʻaʻole i hoʻopiha piha ʻia.
ʻO GB / T 5781-2016 "Hexagon Head Bolts Full Thread Class C" a me GB / T 5783-2016 "Hexagon Head Bolts Full Thread" he mau kaula wili piha.
ʻO GB / T 5781-2016 "Hexagon Head Bolts Full Thread Grade C" ua like ia me GB / T 5780-2016 "Hexagon Head Bolts Grade C" koe wale nō ka hana ʻana o ka huahana i ke kaula piha.
ʻO GB / T 5783-2016 "Hexagon head bolts me ka piha piha" like ia me GB / T 5782-2016 "Hexagon head bolts" koe wale nō ka huahana i hana ʻia me ke kaula piha a ʻo ka lōʻihi nominal o ka kikoʻī i makemake ʻia a hiki i ka 200mm.
No laila, i ka nānā 'ana ma hope, he mea pono e kūkākūkā i ka likeʻole ma waena o GB / T 5780-2016 "Hexagon Head Bolts Class C" a me GB / T 5782-2016 "Hexagon Head Bolts".
2. Nā māka huahana like ʻole:
Hoʻokaʻawale ʻia nā māka huahana o nā bolts i nā māka A, B a me C. Hoʻoholo ʻia ka pae huahana e ka nui o ka hoʻomanawanui. ʻO kahi māka ka pololei loa, a ʻo ka māka C ka mea liʻiliʻi loa.
ʻO GB/T 5780-2016 "Hexagon head bolts C grade" e kuhikuhi ana i ka C grade precision bolts.
ʻO GB / T 5782-2016 "Hexagon head bolts" e kuhikuhi i nā bolts me ka pololei o ka pae A a me ka helu B.
Ma ke kūlana GB/T 5782-2016 "Hexagon Head Bolts", hoʻohana ʻia ka Papa A no nā bolts me d=1.6mm～24mm a me l≤10d a i ʻole l≤150mm (e like me ka waiwai liʻiliʻi); Hoʻohana ʻia ka papa B no nā bolts me ka d>24mm a i ʻole Bolts me ka l>10d a i ʻole l>150mm (ʻoi aku ka liʻiliʻi).
E like me ke kūlana aupuni GB/T 3103.1-2002 "Tolerance Bolts, Screws, Studs and Nuts for Fasteners", ʻo ka pae hoʻomanawanui ʻana o ke kaula waho o nā bolts me ka pololei o ka papa A a me B "6g"; ʻO ka pae hoʻomanawanui o ke kaula waho he "8g"; ʻokoʻa nā pae hoʻomanawanui ʻē aʻe o nā bolts e like me ka pololei o nā māka A, B, a me C.
3. Nā waiwai mechanical like ʻole:
E like me nā ʻōlelo a ka National Standard GB / T 3098.1-2010 "Mechanical Properties of Fasteners Bolts, Screws and Studs", nā ʻano mechanical o nā bolts i hana ʻia me ke kila kalapona a me ke kila kila ma lalo o ke ʻano o ke ʻano o ke kaiapuni o 10 ℃ ~ 35 ℃ He 10 pae, 4.6, 4.8, 5.6, 5.8, 6.8, 8.8, 9.8, 10.9, 12.9, 12.9.
E like me nā ʻōlelo o ka National Standard GB / T 3098.6-2014 "Mechanical Properties of Fasteners - Stainless Steel Bolts, Screws and Studs", ma lalo o ke kūlana o ke kaiapuni o 10 ℃ ~ 35 ℃, nā māka hana o nā bolts i hana ʻia me ka stainless. ʻo ke kila penei:
ʻO nā bolts i hana ʻia me nā austenitic stainless steels (me A1, A2, A3, A4, A5 pūʻulu) he mau papa waiwai mechanical 50, 70, 80. ka hui kila, a ʻo ka ʻāpana ʻelua e hōʻailona i ka papa hana, hoʻokaʻawale ʻia e nā kaha, e like me A2-70, ka mea like ma lalo)
ʻO nā bolts i hana ʻia me ka hui C1 martensitic stainless steel i loaʻa nā māka waiwai mechanical o 50, 70, a me 110;
ʻO nā bolts i hana ʻia i ka hui C3 martensitic stainless steel he papa waiwai mechanical o 80;
ʻO nā bolts i hana ʻia me ka hui C4 martensitic stainless steel he mau māka waiwai mechanical o 50 a me 70.
ʻO nā bolts i hana ʻia me nā kila stainless martensitic F1 loaʻa nā waiwai mechanical grade 45 a me 60.
Wahi a ke kūlana aupuni GB/T 3098.10-1993 "Nā waiwai mīkini o nā mea hoʻopili - Bolts, screws, studs a me nā nati i hana ʻia i nā metala non-ferrous":
ʻO nāʻano mechanical o nā kī i hanaʻia me ke keleawe a me ke keleawe: CU1, CU2, CU3, CU4, CU5, CU6, CU7;
ʻO nāʻano mechanical o nā bolts i hanaʻia me ka alumini a me nā alumini alumini: AL1, AL2, AL3, AL4, AL5, AL6.
ʻO ke kūlana aupuni GB/T 5780-2016 "Class C Hexagon Head Bolts" he mea kūpono ia no ka C grade hexagon head bolts me nā kiko kiko M5 a i ka M64 a me nā māka hana 4.6 a me 4.8.
ʻO ke kūlana aupuni GB / T 5782-2016 "Hexagon head bolts" kūpono i nā kikoʻī kikoʻī M1.6～M64, a ʻo nā māka hana he 5.6, 8.8, 9.8, 10.9, A2-70, A4-70, A2-50, A4-50, Papa A a me B hex poʻo bolts no CU2, CU3 a me AL4.
ʻO ka mea i luna aʻe ka ʻokoʻa nui ma waena o kēia mau 4 bolts maʻamau.
Ma nā hoʻohana pono, hiki ke hoʻohana ʻia nā bolts piha ma kahi o nā bolts non-full-threaded, a hiki ke hoʻohana ʻia nā bolts kiʻekiʻe ma kahi o nā bolts haʻahaʻa haʻahaʻa.
Eia naʻe, ʻoi aku ka maikaʻi o nā bolts piha piha o nā kikoʻī like ma mua o nā bolts piha ʻole, a ʻoi aku ka uku o nā māka hana kiʻekiʻe ma mua o nā māka haʻahaʻa.
No laila, i nā manawa maʻamau, pono e koho ʻia nā bolts e like me nā pono maoli, a i nā manawa kūikawā wale nō e "hoʻololi i nā hewa āpau" a i ʻole "hoʻololi i nā kiʻekiʻe me nā haʻahaʻa".
