Zisetyenziswa njani izikrufu zokuZimbela

Uphahla

I-self-drilling screws yophahla lwentsimbi yenzelwe ngokukodwa kunye ne-washer ukwenza isitywina esiqinileyo xa uqiniswa. Njengazo zonke izikrufu zokuzibhobhoza, zinendawo yokubhola eyenza ukuba ifakwe ngokukhawuleza kwaye kulula.

Ukuhombisa

Ngaphambi kokuphuhliswa kwe-screw self-drilling, abakhi kwakufuneka baqhube imingxuma yokulinga ngaphambi kokufaka izikrufu. I-self-drilling screws iye yaphelisa imfuno yeli nyathelo elongezelelweyo, eliye lanciphisa ixesha lemisebenzi kwaye lenza inkqubo isebenze ngakumbi. Inkqubo iyonke inokwenziwa kwikota yexesha elithathiweyo phantsi kwendlela yo-pre drill.

Inkqubo iyonke inokwenziwa kwikota yexesha elithathiweyo phantsi kwendlela yokomba yangaphambili.

Iphepha leMetal

Amacwecwe esinyithi asetyenziselwa ukwenza isakhelo kwiimveliso ezahlukeneyo. Ukukhawulezisa inkqubo yokuvelisa kunye nokuqinisekisa uxhulumaniso oluqinileyo, i-self-drilling screws isetyenziswa njenge-fasteners. Ingcebiso efana ne-drill ye-self-drilling screws ikhethwa ngaphezu kwezinye iindlela zokuziqinisa ngenxa yokusebenza kwayo. Amashishini asebenzisa izikrufu zokuzibhobhoza zokuqinisa intsimbi aquka ukwakhiwa kweemoto, ukwakha, kunye nokuveliswa kwefenitshala.

Uyilo kunye nokwakhiwa kwe-self-drilling screws ivumela ukuba bagqobhoze i-20 ukuya kwi-14 ye-metal gauge.

Ezonyango

I-self-drilling locking screws isetyenziswa kwintsimi yezonyango ukwenzela utyando lwamathambo, ukutshintshwa kwamalungu, kunye nokulungiswa kwezicubu kunye nemisipha. Njengezinye izicelo, zikhethwa ngaphezu kwezinye iindlela zokuqinisa isantya ezinokuthi zifakwe ngaso. Iimfuno zokusetyenziswa kwazo ziquka ukulinganiswa ngokuchanekileyo kobude babo kunye nokuqinisekiswa kokuzinza kwe-biomechanical.

Ukusakhelo

Izikrufu zokuzibhomba ezenza ifreyimu kufuneka zikwazi ukusika izikhonkwane zentsimbi. Zineentloko ezikhethekileyo ezenzelwe ukunciphisa itorque kodwa zinamandla okubamba akhethekileyo. Bayakwazi ukuqhuba ngeentsimbi ukuya kuthi ga kwi-intshi ye-0.125 ubukhulu kunye nesantya se-RPM ye-1500. Ziza kwiindidi zetsimbi ukuze zilungele ukusebenza kunye nokusetyenziswa.

Kungakhathaliseki ukuba izinto eziza kuqhutyelwa yintsimbi yentsimbi okanye i-gauge yensimbi enzima (phakathi kwe-12 ukuya kwi-20 gauge), i-self-drilling screws inokuxhuma ngokulula kwaye isakhelo isakhiwo.

I-Drywall

Isici esikhethekileyo se-drywall self-drilling screws yintloko yabo ye-countersink ehambelana kakuhle ne-drywall ngaphandle kokukrazula okanye ukonakalisa iphepha kwaye iphephe iipopu zentloko. Ngokuqhelekileyo zigqunywe kwizicelo zangaphakathi kwaye ziza ngamanani 6, 7, 8, kunye ne-10 ye-diameter. Ziyakwazi ukuguquguquka ngokwaneleyo ukuba zifakwe kwiiplanga okanye kwiintsimbi zetsimbi kwaye zibandakanya iintambo eziqengqelekayo zokomeleza amandla kunye nokubamba amandla.
