1. Inkcazo kunye noLwakhiwo oluSisiseko

Inkcazo: I-galvanized screw licandelo lothumelo elifakwe kwi-zinc layer (i-zinc ene-electroplated okanye i-hot-dip zinc) kumphezulu we-screw. Isetyenziswa ikakhulu ukuguqula isindululo esijikelezayo sibe sisindululo somgca kwaye sinamandla okuchasa ukubola.

Amantongomane okutshixa inayiloni zizinto eziyimfuneko kumashishini ahlukeneyo, abonelela ngezisombululo ezikhuselekileyo zokuqinisa usetyenziso olwahlukeneyo. Ngoyilo lwazo olulodwa kunye nokusebenza okuthembekileyo, la mandongomane abonelela ngokuthembeka kunye noxolo lwengqondo.

Iibholiti zediphu ezishushu ziziqhoboshi ezenza umaleko wentsimbi ye-zinc phezu komhlaba ngenkqubo yokugalela idiphu eshushu.

Iibholiti ze-B7 zizibophelelo eziphezulu zokuqina ezisetyenziswa ngokubanzi kumashishini ahlukeneyo ngenxa yeempawu zabo ezibalaseleyo kunye nokuqina.

Iibholithi zokuthwala zihlulwe zibe ziibholiti ezinkulu ze-semi-round head carriage bolts (ezihambelana nemigangatho ye-GB/T14 kunye ne-DIN603) kunye neebholiti ezincinci ze-semi-round head carriage bolts (ezihambelana ne-GB / T12-85 eqhelekileyo) ngokobukhulu bentloko. Ibholithi yokuthwala luhlobo lwe-fastener olubandakanya intloko kunye ne-screw (i-cylinder enemicu yangaphandle). Kufuneka idityaniswe ne nut kwaye isetyenziselwa ukubopha iindawo ezimbini ngemingxuma.
