1.Umqondo
Ibhawodi yangaphandle ene-hexagonal iyisesekeli sensimbi, esaziwa nangokuthi isikulufu esine-hexagonal yangaphandle, isikulufu sangaphandle esine-hexagonal noma ibholidi yangaphandle ene-hexagonal.

2.Ukwelashwa kwendawo
Enqubweni yokukhiqiza amabhawodi, ukwelashwa okungaphezulu kungenye yezixhumanisi ezibalulekile. Ingenza ingaphezulu lebhawodi lihlangabezane nezidingo ezithile futhi lithuthukise ukumelana nokugqwala kwalo, amandla kanye nobuhle.
Kunezinhlobo eziningi zezindlela zokwelapha ezingaphezulu zamabhawodi, ezijwayelekile yilezi ezilandelayo:
I-galvanizing: Amabhawodi acwiliswa kwisisombululo se-zinc, futhi i-zinc imbozwe phezu kongqimba lwamabhawodi ngongqimba ngokusebenzisa ukusabela kwe-electrochemical, okuwenza angangeni nokugqwala futhi amelane nokugqwala.
I-Hot-dip galvanizing: Ngemva kokuba amabhawodi enziwe, acwiliswa oketshezini lwezinki oluncibilikisiwe, bese kwakheka ungqimba lwezinc phezulu ngokusabela kwamakhemikhali ukuze kuzuzwe imiphumela elwa nokugqwala, ukumelana nokugqwala neminye imiphumela.
Ukwelashwa kokumnyama: Ifilimu ye-oxide yensimbi emnyama yenziwa phezu kwebhawodi ngokusabela kwamakhemikhali ukuze kuthuthukiswe ukumelana nokugqwala.
Ukwelashwa kwe-Phosphating: Gxilisa ibhawodi kusisombululo se-phosphating ukuze wenze ifilimu ye-phosphating phezulu ukuze uthuthukise ukumelana nokugqwala.
Ukwelashwa kokuqina: Ngokwelashwa kokushisa noma ukufafaza okungaphezulu, ungqimba lokumboza olunokuqina okuphezulu luyakhiwa ebusweni bebhawodi ukuze kuthuthukiswe amandla alo nokumelana nokugqoka.
Okungenhla kuyindlela evamile yokwelashwa kwe-bolt surface. Izindlela zokwelashwa ezihlukene zihambisana nezimo ezihlukene zohlelo lokusebenza kanye nezidingo. Lapho wenza ukwelashwa kwe-bolt surface, kufanele kwenziwe ngokuhambisana nezindinganiso ezihambisanayo kanye nokucaciswa kokuqinisekisa ukuthi ama-bolts aphathwe ahlangabezana nezidingo zokusebenza ezifanele.

3. Ukusebenza kwezinga
Ilebula yebanga lokusebenza yebhawodi yangaphandle ene-hexagonal iqukethe izingxenye ezimbili zezinombolo, ngokulandelana kwazo ezimelela inani lamandla ashubile okuzisholo kanye nesilinganiso samandla esivuno sento yebhawodi.
Isibonelo, ibhawudi elinezinga lokusebenza 4.6 lisho:
a. Amandla okuqina okuzisholo wento yebhawodi afinyelela ku-400MPa;
b. Isilinganiso sesivuno-amandla we-bolt material ngu-0.6;
c. Amandla okuvunwa okuzisholo wento yebhawodi afinyelela ku-400×0.6=240MPa ezingeni
Izinga lokusebenza 10.9 amabhawodi amandla aphezulu, ngemva kokwelashwa ukushisa, angafinyelela:
a. Amandla okuzisholo okuqinile wento yebhawodi afinyelela ku-1000MPa;
b. Amandla okukhiqiza ajwayelekile wento yebhawodi afinyelela ku-1000×0.9=900MPa.

4. Umehluko phakathi kwamabhawodi angaphandle ane-hexagonal ajwayelekile kanye namabhawodi angaphandle ane-hexagonal enamandla amakhulu
Amabhawodi ajwayelekile angama-hexagonal angasetshenziswa kabusha, kodwa amabhawodi anamandla aphezulu awakwazi ukuphinda asetshenziswe.
Amabhawodi aqinile ngokuvamile enziwa ngensimbi enamandla angu-45 (8.8s), 20MmTiB (10.9S), futhi angamabhawodi acindezelwe. Ngezinhlobo zokungqubuzana, sebenzisa i-torque wrench ukuze usebenzise i-prestress ecacisiwe, kanye nezinhlobo ezithwala ingcindezi, khulula ikhanda le-torx. Amabhawodi ajwayelekile enziwa ngensimbi ejwayelekile (Q235) futhi adinga ukuqiniswa kuphela.
Amabhawodi ajwayelekile ngokuvamile eba grade 4.4, grade 4.8, grade 5.6 kanye grade 8.8. Amabhawodi aqine kakhulu ngokuvamile yibanga lesi-8.8 kanye nebanga le-10.9, kanti ibanga le-10.9 yilona elivame kakhulu.
Izimbobo ezikulufi zamabhawodi ajwayelekile azikho zikhulu kakhulu kunalezo zamabhawodi anamandla amakhulu. Eqinisweni, izimbobo zamabhawodi ezivamile zincane uma kuqhathaniswa.
