HEX HEAD BOLTS–He hoʻolauna ʻenehana piha i nā mea paʻa ikaika kiʻekiʻe no nā noi koi.

2026-08-31

1. Hoʻolauna

Hōʻike ka papa 10.9 Dacromet hexagon head bolts i ka papa premium o nā mea hoʻopaʻa ikaika kiʻekiʻe i hoʻohana nui ʻia i nā kaʻa, kūkulu, makani makani, mīkini kaumaha, a me nā noi ʻoihana. Hoʻohui kēia mau bolts i ʻekolu mau hiʻohiʻona koʻikoʻi: ʻo ka hana mīkini ʻoi aku ka maikaʻi o ka papa waiwai 10.9, ka geometry versatile a hilinaʻi o ka hoʻolālā poʻo hexagonal, a me ka pale corrosion koʻikoʻi i hāʻawi ʻia e Dacromet (zinc-flake) coating.

2. Papa Waiwai 10.9 — Ikaika Mechanical

Ua wehewehe ʻia ka papa waiwai 10.9 ma ISO 898-1 (Nā waiwai mīkini o nā mea hoʻopaʻa i hana ʻia me ke kila kalapona a me ke kila kila - Māhele 1: Bolts, screws a me nā studs). ʻO ka inoa "10.9" e hōʻike ana i ka ikaika tensile nominal o 1000 MPa a me kahi ratio yield-to-tensile ma kahi o 0.9. ʻO kēia mau mea hoʻopaʻa maʻamau i hana ʻia mai nā mea hao hao i hoʻopaʻa ʻia a hoʻoheheʻe ʻia (e laʻa, 35CrMo, 42CrMo, a i ʻole nā hao boron) a kūpono ia no nā hana hoʻolālā kiʻekiʻe a me ka ikaika.

Nā Waiwai Mekani Nui (ISO 898-1)

Waiwai	Nominal	liʻiliʻi	Unite
Ka ikaika wili Rm	1000	1040	MPa
ʻO ke koʻikoʻi o ka hōʻoiaʻiʻo / ʻoi aku ka ikaika Rp0.2	900	940	MPa
ʻO ke koʻikoʻi ma lalo o ka ukana hōʻoiaʻiʻo Sp	830	—	MPa
ʻO ka elongation ma hope o ka haʻi ʻana A	—	9	%
Vickers paakiki HV	—	320 – 380	HV
ʻO Rockwell paʻakikī HRC	—	32 – 39	HRC

Hoʻohālikelike ʻia me ka papa waiwai 8.8, hāʻawi ka Papa 10.9 ma kahi o 25-30% kiʻekiʻe kiʻekiʻe o ka tensile a ʻoi aku ka nui o ka hiki ke hoʻouka ʻia. ʻO kēia ka mea i koho maikaʻi ʻia no nā hui koʻikoʻi i nā ʻenekini, chassis, structural steelwork, a me nā mea kaumaha kahi e pono ai ka hoʻemi kaumaha a me ka hana kiʻekiʻe.

3. Hexa Bolts — Hoʻolālā & Kūlana

ʻO nā kī poʻo hexagon (i kapa ʻia ʻo hex bolts) ka mea hoʻohana nui ʻia i nā mea hoʻopaʻa hoʻopaʻa waho. Hāʻawi ke poʻo ʻeono ʻaoʻao i ka hoʻoili torque maikaʻi loa me nā wrenches open-end maʻamau a hiki i ke komo ʻana mai nā kihi he nui. ʻElua mau kūlana koʻikoʻi honua e hoʻokele i nā metric hex bolts:

ISO 4014 / DIN 931 - Hoʻopili ʻia i kahi ʻāpana (shank ma lalo o ke poʻo)
ISO 4017 / DIN 933 — Pili piha

ʻOi aku ka maikaʻi o nā bolts ʻāpana-wili (ISO 4014) i ka wā e hana ai ka mokulele ʻāwī ma luna o ka shank ʻaʻole i ulana ʻia no ka hiki ke ʻoki ʻoi aku ka nui, a i ʻole ke koi ʻia ka lōʻihi pipili pololei. Koho ʻia nā bolts piha no ka versatility a i ka wā e komo ai ka lōʻihi piha i kahi nati a i ʻole puka paʻi.

Nā Ana Maʻamau (Nā Nui i koho ʻia, ISO 4014 / DIN 931)

Nui inoa	Pitch (mm)	Ma nā Pāpā s (mm)	Kiʻekiʻe Poʻo k (mm)	Loihi Uila b ≤125 mm	Nui Uila
M8	1.25	13	5.3	22	13
M10	1.5	16 / 17	6.4	26	16 / 17
M12	1.75	18 / 19	7.5	30	18 / 19
M16	2.0	24	10.0	38	24
M20	2.5	30	12.5	46	30
M24	3.0	36	15.0	54	36

'Ōlelo Aʻo: He ʻokoʻa iki paha ka nui o nā ana ma waena o ka pūʻulu ISO a me DIN no kekahi mau nui (e laʻa, M10 a me M12). E hōʻoia mau i ke kūlana kūpono no ka noi. Hōʻike nā helu huahana A a me B i nā ʻae ʻana o ka nui; ʻOi aku ka paʻa o ka papa A a hoʻohana mau ʻia no nā anawaena liʻiliʻi.

Pono o ka Hexagon Head Design

ʻO ka hiki ke hoʻoili torque kiʻekiʻe me nā mea hana maʻamau
Loaʻa maikaʻi ma nā wahi paʻa mai nā kihi ʻeono
ʻO ka hana kūʻai kūpono a me ka loaʻa ākea
Hoʻohālikelike me ka piha piha o nā nati, nā mea holoi, a me nā mea laka

4. ʻO ka uhi ʻana o Dacromet — Hoʻopaʻa ʻana i ka ʻino

ʻO Dacromet kahi ʻenehana hoʻopili zinc-flake proprietary (i hoʻomohala mua ʻia e Metal Coatings International). Loaʻa iā ia nā ʻāpana zinc a me aluminika i hoʻopaʻa ʻia i loko o kahi mea hoʻopaʻa kino, i hoʻohana ʻia e ka dip-spin a i ʻole nā ʻano hoʻoheheʻe ʻia a hoʻōla ʻia ma kahi o 300-340 °C. Hāʻawi ke kiʻi ʻoniʻoni lahilahi, mānoanoa, hina-hinahina multi-mechanism me ka pilikia ʻole o ka hydrogen embrittlement - he pono koʻikoʻi no nā mea hoʻopaʻa ikaika kiʻekiʻe e like me ka Papa 10.9 a me 12.9.

Nā ʻano hana nui

ʻĀpana	Waiwai maʻamau / hana
Mānoanoa uhi	5 – 15 μm (Papa A ≈ 5 μm; Papa B ≈ 8 μm)
Paʻakai paʻakai kūʻokoʻa (ASTM B117)	500 - 1000+ hola i ka ʻulaʻula (e pili ana i ka papa)
Kūleʻa wela	A hiki i 300 °C mau (e mau ana ka pale)
ʻO ka pōʻino o ka hydrogen embrittlement	ʻAʻohe (kaʻina non-electrolytic, ʻaʻohe pickling acid)
Coefficient of friction	0.12 - 0.18 (me nā ʻano lubricant e like me Dacromet 500)
Ka nana aku	Metala kala-hina; uhi ʻaʻahu ma luna o nā kaula

Hoʻohālikelike me nā ʻāpana ʻokoʻa maʻamau

Hiʻona	Electro Zinc	Hoʻohu wela	ʻO Dacromet
mānoanoa	5–15 μm	40–85 μm	5–15 μm
Paʻakai paʻakai (ʻula ʻula)	72–240 h	400–800 hola	500–1000+ hola
H₂ pilikia embrittlement	Kiʻekiʻe	I kēia manawa	ʻAʻohe
Ka hopena kūpono o ka milo	Haʻahaʻa	Kiʻekiʻe (pono pinepine i ka nui)	liʻiliʻi
Kūpono no 10.9+	kaupalena	Pono e akahele	Maikaʻi

Ma muli o ke kaʻina hana Dacromet ʻaʻohe hana electrochemical hydrogen a ʻaʻohe hoʻopaʻapaʻa ʻawaʻawa ʻawaʻawa, ʻo ia ka mea i makemake ʻia (a koi pinepine ʻia) no ka papa 10.9 a me nā mea hoʻopaʻa kiʻekiʻe i nā kikoʻī o ka automotive a me ka hoʻolālā.

5. Nā Pono Hoʻohui a me nā noi maʻamau

Ke hui pū ʻia ka ikaika o ka Papa 10.9, ka geometry poʻo hexagonal, a me ka uhi ʻana o Dacromet, hāʻawi ka mea hoʻopaʻa hopena i kahi kaulike koʻikoʻi o ka hana mechanical, ʻoluʻolu o ka hui ʻana, a me ka lōʻihi lōʻihi i nā kaiapuni corrosive.

Nā Pōmaikaʻi Nui

1. Hiki i ka hoʻouka ʻana o ka puʻu kiʻekiʻe - hiki i nā hoʻolālā hui māmā a me ka hilinaʻi kiʻekiʻe ma lalo o ka haʻalulu a me nā haʻahaʻa ikaika.

2. ʻOi aku ka maikaʻi o ka corrosion - ʻoi aku ka nui o ka hana paʻakai ma mua o ka hoʻoheheʻe zinc maʻamau me ka mālama ʻana i ka pololei o ke kaula.

3.Hydrogen-embrittlement manuahi - pono palekana hiʻona no nā mea hoʻopaʻa kila ikaika.

4.Controlled friction - lubricated Dacromet variants e hāʻawi i ka wānana torque-tension pilina, hoʻomaikaʻi i ka hui like.

5. Thermal paʻa - mau ka pale i nā wela kiʻekiʻe i ʻike ʻia i loko o nā keʻena mīkini a me nā mea hana ʻoihana.

Nā Māhele Hoʻohana maʻamau

Kaʻa: chassis, hoʻokuʻu ʻia, nā puʻu mīkini, nā ʻāpana powertrain
Ike makani: nā ʻūhā hale kiaʻi, nā hale nacelle, nā heleuma kumu
ʻO ke kūkulu ʻana a me ka hana ʻino: nā alahaka kila, nā hale kiaʻi hoʻouna, ke alahao
ʻO nā mīkini mahiʻai a me ke kūkulu hale e hana ana ma waho
Nā lako kai a me waho (me ke koho papa kūpono)

6. Ka hopena

Hāʻawi ka papa 10.9 Dacromet hexagon head bolts i kahi hui hilinaʻi o ka ikaika tensile kiʻekiʻe, geometry hoʻonohonoho pono, a me ka pale corrosion lōʻihi. Ma ka hoʻokō ʻana i nā koi mechanical koʻikoʻi o ISO 898-1 Class 10.9, e hoʻokō ana i nā kūlana dimensional i hoʻokumu ʻia e like me ISO 4014, a me ka hoʻohana ʻana i ka hydrogen-embrittlement-free zinc-flake coating, hāʻawi kēia mau mea hoʻopaʻa i nā ʻenekinia me kahi hopena i hōʻoia ʻia no nā hui koʻikoʻi i ʻike ʻia i nā pilikia mechanical a me nā wahi ʻino.

Mamua. Aʻe.
