HEX HEAD BOLTS- Hordhac Farsamo oo Dhameystiran Xidhiidhiyayaasha Xoogga Sare ee Dalbashada Codsiyada

2026-08-31

1. Hordhac

Fasalka 10.9 Dacromet hexagon bolts waxay ka dhigan yihiin dabaq qaali ah oo xirxirayaal aad u sarreeya oo si ballaaran loogu isticmaalo baabuurta, dhismaha, tamarta dabaysha, mashiinnada culus, iyo codsiyada kaabayaasha. Boorarkani waxay isku daraan saddex sifo oo muhiim ah: waxqabadka farsamada sare ee heerka hantida 10.9, joomatari la isku halayn karo oo naqshadaynta madaxa lix geesoodka ah, iyo ilaalinta daxalka ee aadka u wanaagsan ee ay bixiso Dacromet (zinc-flake).

2. Heerka Hantida 10.9 - Xoogga Farsamada

Heerka hantida 10.9 waxaa lagu qeexay TS EN ISO 898-1 (Guryaha makaanikada ee xirmooyinka ka samaysan birta kaarboonka iyo birta aluminiumka - Qeybta 1: Bolts, boolal iyo birta). Magacaabista "10.9" waxay tusinaysaa cudud magaceed oo ah 1000 MPa iyo saamiga wax-soo-saarka ee ku dhawaad 0.9. Xidhiidhiyayaashan waxaa sida caadiga ah laga soo saaraa birta damiyay iyo kuwa dabcay (tusaale, 35CrMo, 42CrMo, ama birta boron) waxayna ku habboon yihiin codsiyo dhismeed oo sarreeya iyo kuwo firfircoon.

Guryaha Makaanikada Furaha ah (ISO 898-1)

Hanti	Magac ahaan	Ugu yar	Unug
Xoog xajin Rm	1000	1040	MPa
Cadaadiska cadaadiska / Awood-soo-saarka Rp0.2	900	940	MPa
Cadaadiska ka hooseeya culeyska Sp	830	—	MPa
Kordhinta jabka ka dib	—	9	%
Vickers qallafsanaanta HV	—	320 - 380	HV
Rockwell hardness HRC	—	32 - 39	HRC

Marka la barbar dhigo heerka hantida ee 8.8, Fasalka 10.9 wuxuu bixiyaa ku dhawaad 25-30 % awoodda xajinta Tani waxay ka dhigaysaa doorashada la door bidayo ee kala-goysyada muhiimka ah ee matoorada, chassis, birta qaab dhismeedka, iyo qalabka culus halkaasoo loo baahan yahay dhimista miisaanka iyo waxqabadka sare.

3. Hexa Bolts — Naqshad & Heerarka

Dhalooyinka madaxa ee saddex geesoodka ah (sida badan loo yaqaan hex bolts) ayaa ah kuwa ugu badan ee la isticmaalo xirmooyinka wax dila ee dibadda ah. Madaxa lixda geesoodka ah wuxuu bixiyaa gudbinta qulqulka heer sare ah oo leh fur-furan heersare ah ama wiish-ka-furan oo u oggolaanaya gelitaanka xaglo badan. Laba halbeeg oo caalami ah ayaa maamula metric hex bolts:

TS EN ISO 4014 / DIN 931 - Qayb ahaan dunta (madaxa hoostiisa)
ISO 4017 / DIN 933 - dun si buuxda

Xirmooyinka qayb ka mid ah (ISO 4014) ayaa la door bidaa marka diyaaradda dhogorta ay tahay inay ku dhaqdo shayga aan xadhigga lahayn ee awoodda xiirid sare, ama marka dhererka isku dhejinta saxda ah loo baahan yahay. Dhalooyinka dunta-buuxa ah ayaa loo doortaa is-bedelka iyo marka dhererka buuxa laga yaabo inuu galo lowska ama dalool la taaban karo.

Cabbirrada caadiga ah (Xajmiga la doortay, ISO 4014 / DIN 931)

Cabbirka Magaca	Dhererka (mm)	Guryaha oo dhan s (mm)	Dhererka madaxa k (mm)	Dhererka xadhigga b ≤125 mm	Cabbirka furaha
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

Fiiro gaar ah: Cabbirrada guryaha dabaqyada ah waxa laga yaabaa inay wax yar ku kala duwanaadaan ISO iyo taxanaha DIN ee cabbirrada qaarkood (tusaale, M10 iyo M12). Had iyo jeer xaqiiji heerka lagu dabaqi karo codsiga. Darajooyinka badeecada A iyo B waxay qeexaan dulqaadka cabbirka; Darajada A way adagtahay waxaana caadi ahaan loo isticmaalaa dhexrooryada yaryar.

Faa'iidooyinka Naqshadeynta Madaxa Hexagon

4. Dacromet - Ilaalinta Daxalka Sare

Dacromet waa tignoolajiyada dahaadhka zinc-flake ee iska leh (asal ahaan waxaa soo saartay Metal Coatings International). Waxay ka kooban tahay jajabyo zinc iyo aluminium ah oo ku xayiran xiraha aan orgaaniga ahayn, lagu dabaqo hababka lagu buufiyo ama lagu buufiyo waxaana lagu daaweeyay qiyaastii 300-340 °C. Filimka khafiifka ah ee cufan, qalinka-cawlan ee ka soo baxay wuxuu bixiyaa ilaalinta daxalka badan ee makaanismka iyada oo aan la helin khatarta hydrogen ebrittlement - faa'iido muhiim ah oo loogu talagalay xirmooyinka xoogga badan sida Fasalka 10.9 iyo 12.9.

Tilmaamaha Waxqabadka Muhiimka ah

Halbeegga	Qiimaha / Waxqabadka Caadiga ah
Dhumucda dahaarka	5 - 15 μm (Darajada A ≈ 5 μm; Fasalka B ≈ 8 μm)
Buufin cusbo dhexdhexaad ah (ASTM B117)	500 - 1000+ saacadood ilaa miridhku guduudan yahay (waxay kuxirantahay darajada)
Iska caabbinta kulaylka	Ilaa 300 °C joogto ah (dahaarka ayaa weli ilaalinaya)
Khatarta qulqulka hydrogen-ka	Midna (nidaam aan elektrolytic ahayn, ma jiro aashito picking)
Isku-dhafka is-jiidhka	0.12 - 0.18 (oo leh noocyo saliid ah sida Dacromet 500)
Muuqashada	Birta qalin-cawlan; daboolka labbiska xitaa dunta

Isbarbardhigga Dahaarka Beddelka Guud

Muuqaal	Electro Zinc	Galvanizing Kulul-Dip	Dacromet
Dhumucda	5-15 μm	40-85 μm	5-15 μm
Buufin milix ah ( miridh cas)	72-240 saac	400-800 saacadood	500-1000+ saac
H₂ khatarta embrittlement	Sare	La joogo	Midna
Saamaynta ku habboon ee xadhigga	Hoose	Sare (badanaa waxay u baahan tahay ka weyn)	Ugu yar
Ku habboonaanta 10.9+	Xaddidan	Taxadir ayaa loo baahan yahay	Aad u fiican

Sababtoo ah habka Dacromet kuma lug yeesho jiil hydrogen-kimikaad ah iyo majirto aashito qallafsan, waa dahaarka la doorbiday (iyo inta badan waa qasab) ee darajada 10.9 iyo xirayaasha sare ee sifooyinka baabuurta iyo qaabdhismeedka.

5. Faa'iidooyinka Isku dhafan & Codsiyada Caadiga ah

Marka darajada 10.9 xoogga, joomatari madaxa laba geesoodka ah, iyo daahan Dacromet la isku daro, xiraha ka soo baxa wuxuu bixiyaa dheelitirnaan heer sare ah oo waxqabadka farsamada ah, ku habboonaanta isu imaatinka, iyo adkeysiga muddada-dheer ee bay'adaha daxalka.

Faa'iidooyinka aasaasiga ah

1.High culeyska culeyska culeyska - wuxuu awood u siinayaa naqshadaha wadajirka ah ee fudud iyo kalsoonida sare ee hoos yimaada gariirka iyo culeysyada firfircoon.

2.Superior iska caabin daxalka - Waxqabadka milix-buufinta fog ka badan dahaaridda zinc caadiga ah iyadoo la ilaalinayo saxnaanta dunta.

3.Hydrogen-embrittlement lacag la'aan ah - muujinta badbaadada lagama maarmaanka u ah xirmooyinka birta ee xoogga badan.

4. Xakamaynta xakamaynta - noocyada Dacromet ee saliidda leh waxay bixiyaan xidhiidho kacsanaan ah oo la saadaalin karo, hagaajinta joogteynta shirarka.

5.Xasiloonida kulaylka - ayaa weli ilaalinaysa heerkulka sarreeya ee la kulma qaybaha mashiinka iyo qalabka warshadaha.

Goobaha Codsiga ee Caadiga ah

Gawaarida: chassis, ganaax, matoorka ku rakibida, qaybaha tareenka
Tamar dabaysha: flanges munaaradda, dhismayaasha nacelle, barroosinnada aasaasiga ah
Dhismaha culus & kaabayaasha: buundooyinka birta, munaaradaha gudbinta, jid tareen
Mashiinada beeraha iyo dhismaha ee ka shaqeeya bannaanka
Qalabka badda iyo badda (oo leh xulasho darajo habboon)

6. Gabagabo

Fasalka 10.9 Dacromet hexagon boolal waxay keenaan isku darka la isku halayn karo ee xoogga xajin sare, joomatari rakibaadda wax ku ool ah, iyo ilaalinta daxalka ee muddada dheer. Iyada oo la buuxinayo shuruudaha farsamada adag ee ISO 898-1 Fasalka 10.9, u hoggaansanaanta heerarka cabbirka ee la aasaasay sida ISO 4014, iyo adeegsiga daahanka-jilicsan ee ka madax-bannaan hydrogen-ka-jilicsan, xirxirayaashani waxay siinayaan injineerada xal la xaqiijiyay oo loogu talagalay kala-goysyada muhiimka ah ee soo gaadhay culeyska farsamada iyo jawiga gardarrada.

Horay Xiga.
