Ingcaciso yeMveliso

Izikrufu zokuzigrumba ngokuzenzela zizikhonkwane eziyilwe ngokukodwa ezidla ngokusetyenziselwa ukufulela izicelo. Ezi zikrufu zenziwe ngenqaku elibukhali elivumela ukuba zibhobhoze kwizinto zokuphahla ezifana nentsimbi, iplastiki, okanye iplanga ngaphandle kwesidingo somngxuma owenziwe ngaphambili. I-screws ibonisa intloko ye-hex okanye intloko ye-washer enika uxhulumaniso olukhuselekileyo phakathi kwezinto zokuphahla kunye nomgangatho wophahla.

Izikrufu zokuzigrumba ezizibhobhozayo zenziwa ngentsimbi engatyiwa okanye igalvanized steel, nto leyo ibanika ukuxhathisa okuphezulu kumhlwa kunye nomhlwa. Izikrufu ziza ngobukhulu obahlukeneyo kunye nobude, kwaye zenzelwe ukumelana neemeko zemozulu ezirhabaxa ezivezwa uphahla.

Olunye lweempawu ezikhethekileyo zezikrufu zokuzigrumba ngokwazo kukukwazi ukwenza isitywina esingangeni manzi esijikeleze umngxuma wesikrufu. Oku kuphunyezwa ngerabha okanye iwasha ye-neoprene efakwe phantsi kwentloko ye-screw, ethi ivale umngxuma kwaye ithintele amanzi ukuba angangeni.
