Ukuthwala umthamo = amandla x indawo
I-Bolt inentambo yesikrufu, indawo yecandelo lomnqamlezo we-M24 ayikho indawo yesangqa sedayamitha engama-24, kodwa yi-353 square mm, ebizwa ngokuba yindawo esebenzayo.
Amandla obunzima beebholiti eziqhelekileyo zeklasi C (4.6 kunye ne-4.8) yi-170N / sq. mm
Emva koko umthamo wokuthwala: 170×353 = 60010N.
Ngokutsho koxinzelelo loxhulumaniso: ihlulwe ibe yimingxuma eqhelekileyo kunye ne-hinged. Ngokwemilo yentloko ngesenti: yiba nentloko enehexagon, intloko engqukuva, intloko eyisikweri, intloko etshonelweyo njalo njalo. Intloko yeHexagon yeyona isetyenziswa kakhulu. Intloko ye-countersunk idla ngokusetyenziswa apho kufuneka uxhulumaniso
Ukukhwela ibholithi yesiNgesi igama le-u-bolt, iindawo ezingekho mgangathweni, imilo i-u-shaped ngoko ke yaziwa ngokuba yi-bolt emilise okwe-u, iziphelo zombini zomsonto zinokudityaniswa kunye ne nut, ikakhulu isetyenziselwa ukulungisa ityhubhu efana umbhobho wamanzi okanye ipleyiti efana nomthombo wemoto, ngenxa yendlela yokulungisa izinto njengabantu abakhwele amahashe, okubizwa ngokuba yi-riding bolt. Ngokobude bomsonto ube ngumsonto opheleleyo kwaye ungeyo-intambo epheleleyo iindidi ezimbini.
Ngokomsonto wamazinyo ahlulwe abe ziindidi ezimbini zamazinyo arhabaxa kunye namazinyo acolekileyo, amazinyo arhabaxa kwiibholiti awabonisi. Iibholithi zihlelwe zibe yi-3.6, 4.8, 5.6, 6.8, 8.8, 9.8, 10.9 kunye ne-12.9 ngokwebakala lokusebenza. Iibholiti ezingaphezulu kwe-8.8 grade (kubandakanywa ne-8.8 grade) zenziwe ngentsimbi ephantsi ye-carbon alloy okanye i-medium carbon steel kwaye ziye zafumana unyango lobushushu (ukucima kunye nokufudumala). Ngokuqhelekileyo zibizwa ngokuba yi-high-strength bolts kwaye ngaphantsi kwe-8.8 grade (ngaphandle kwe-8.8 grade) zibizwa ngokuba ziibholiti eziqhelekileyo.
Iibholiti eziqhelekileyo zinokwahlulwa zibe ngamabakala A, B kunye no-C ngokuchaneka kwemveliso. Amabanga A kunye no-B ziibholiti ezicolisisiweyo kwaye amabakala C azibholithi ezirhabaxa. Kwiibholiti zokudityaniswa kwesakhiwo sentsimbi, ngaphandle kokuba kuphawulwe ngokukodwa, ngokuqhelekileyo iibholithi zeklasi ezirhabaxa zeC
