1. Ingcamango
I-bolt yangaphandle ene-hexagonal sisixhobo sesinyithi, esaziwa ngokuba yi-screw yangaphandle ene-hexagonal, i-screw yangaphandle ene-hexagonal okanye i-bolt yangaphandle ene-hexagonal.

2. Unyango lomphezulu
Kwinkqubo yokwenziwa kweebholiti, unyango lomphezulu yenye yeekhonkco ezibalulekileyo. Ingenza umphezulu webholiti uhlangabezane neemfuno ezithile kwaye iphucule ukumelana nokugqwala, amandla kunye nobuhle bawo.
Kukho iintlobo ezininzi zeendlela zonyango lomphezulu weebholiti, ezixhaphakileyo zezi zilandelayo:
Ukugaya ngentsimbi: Iibholithi zintywiliselwa kwisisombululo se-zinc, kwaye i-zinc igqunywe phezu komphezulu webholithi ngelaphu ngelaphu ngokusebenzisa i-electrochemical reaction, nto leyo eyenza ukuba zingagqwali kwaye zingagqwali.
Ukugalela igesi ngobushushu: Emva kokuba iibholithi zenziwe, zifakwa kulwelo lwezinc olunyibilikisiweyo, kwaye umaleko wezinc wenziwa phezu komhlaba nge-chemical reaction ukuze kufezekiswe imiphumo yokulwa nomhlwa, ukumelana nokugqwala kunye nezinye iziphumo.
Unyango lokwenziwa mnyama: Ifilimu ye-oxide yesinyithi emnyama yenziwa phezu komphezulu webholiti nge-chemical reaction ukuphucula ukumelana kwayo nokugqwala.
Unyango lwe-phosphate: Nciphisa i-bolt kwisisombululo se-phosphate ukuze wenze ifilimu ye-phosphate kumphezulu ukuze kuphuculwe ukumelana kwayo nokugqwala.
Unyango lokuqina: Ngokusebenzisa ubushushu okanye ukutshiza umphezulu, umaleko wokwaleka onobunzima obuphezulu wenziwa phezu komphezulu webholiti ukuphucula amandla ayo kunye nokumelana nokuguguleka.
Ezi zingentla ziindlela eziqhelekileyo zonyango lomphezulu webholiti. Iindlela ezahlukeneyo zonyango zihambelana neemeko ezahlukeneyo zokusetyenziswa kunye neemfuno. Xa kusenziwa unyango lomphezulu webholiti, kufuneka lwenziwe ngokuhambelana nemigangatho kunye neenkcukacha ezifanelekileyo ukuqinisekisa ukuba iibholiti eziphathweyo ziyahlangabezana neemfuno zokusebenza ezifanelekileyo.

3. Ukusebenza kwinqanaba
Ileyibhile yomgangatho wokusebenza kwebholti yangaphandle enehexagonal inamacandelo amabini amanani, amele ngokwahlukeneyo ixabiso lamandla okutsalwa kunye nomlinganiselo wamandla okukhupha wezinto zebholti.
Umzekelo, ibholiti enenqanaba lokusebenza elingu-4.6 ithetha:
a. Amandla okutsalwa okuqhelekileyo kwezinto zebholithi afikelela kwi-400MPa;
b. Umlinganiselo we-yield-strength wezinto ze-bolt yi-0.6;
c. Amandla e-nominal yield yezinto ze-bolt afikelela kwinqanaba le-400×0.6=240MPa
Inqanaba lokusebenza le-10.9 bolts ezinamandla aphezulu, emva konyango lobushushu, zinokufikelela:
a. Amandla okutsalwa okuqhelekileyo kwezinto zebholithi afikelela kwi-1000MPa;
b. Amandla e-nominal yield yezinto ze-bolt afikelela kwi-1000×0.9=900MPa.

4. Umahluko phakathi kweebholiti eziqhelekileyo zangaphandle ezineehexagonal kunye neebholiti zangaphandle ezineehexagonal ezinamandla aphezulu
Iibholiti eziqhelekileyo ezineehexagonal zingasetyenziswa kwakhona, kodwa iibholiti ezinamandla aphezulu azinakusetyenziswa kwakhona.
Iibholiti ezinamandla aphezulu zihlala zenziwe ngentsimbi enamandla kakhulu enguNombolo 45 (8.8s), 20MmTiB (10.9S), kwaye ziibholiti ezixineneyo. Kwiintlobo zokungqubana, sebenzisa isikrufu se-torque ukufaka i-prestress echaziweyo, kwaye kwiintlobo ezithwala uxinzelelo, khupha intloko ye-torx. Iibholiti eziqhelekileyo zihlala zenziwe ngentsimbi eqhelekileyo (Q235) kwaye zifuna ukuqiniswa kuphela.
Iibholiti eziqhelekileyo zihlala zikwibanga lesi-4.4, ibanga lesi-4.8, ibanga lesi-5.6 kunye nebanga lesi-8.8. Iibholiti ezinamandla aphezulu zihlala zikwibanga lesi-8.8 kunye nebanga le-10.9, kwaye ibanga le-10.9 lelona lixhaphakileyo.
Imingxuma yezikrufu zeebholiti eziqhelekileyo ayinkulu kangako kuneyeebholiti ezinamandla aphezulu. Enyanisweni, imingxuma eqhelekileyo yeebholiti incinci kakhulu.
