Maninzi amagama e-bolt engaphandle ye-hexagonal bolt, umzekelo, inokubizwa ngokuba yi-bolt yangaphandle ye-bolt, umzekelo, inokubizwa ngokuba yi-bolt yangaphandle ye-hexagonal bolt. Ikwabizwa ngokuba yi-bolt yangaphandle enamacala. Konke oku kuthetha into enye. Kungenxa yokuba imikhwa yobuqu yahlukile. Emva unyango umphezulu galvanizing komhlaba, isiphumo anti-umhlwa iyafezekiswa.
1. iibholiti eziqhelekileyo zahlulwe zangumhla ka-a, b no-c. Ezi zimbini zokuqala ziibholiti ezicokisekileyo, ezingafane zisetyenziswe. Ngokubanzi, iibholiti eziqhelekileyo zibhekisa kwiClass C iibholiti eziqhelekileyo.
2. Udidi C iibholiti eziqhelekileyo zisetyenziswa kunxibelelwano lwethutyana kunye nokunxibelelana okufuna ukudilizwa. Iibholiti eziqhelekileyo ezisetyenziswa rhoqo kulwakhiwo zi-M16, M20 kunye neM24. Ezinye iibholiti ezingekho mgangathweni kushishino ngoomatshini zinokuba nobubanzi obukhulu kunye neenjongo ezizodwa.
amandla aphezulu okuxubana okubamba ibholiti
3. Izinto ezibonakalayo ze-bolt yamandla ahlukileyo kuleyo ye-bolt yesiqhelo. Iibholiti zamandla aphezulu zisetyenziselwa unxibelelwano olusisigxina. Zidla ngokusetyenziswa M16 ~ M30.
