Yintoni izikrufu zeDekhi?

Xa usakha umgangatho, kuya kufuneka usebenzise uhlobo olululo lwezikrufu. Uninzi lweedekhi zibandakanya amaplanga. Ezi planga, ngokuqinisekileyo, kufuneka zikhuselwe kwisakhelo ngezikrufu. Kunokuba usebenzise izikrufu zomthi zemveli, nangona kunjalo, kuya kufuneka uqikelele ukusebenzisa izikrufu zedekhi. Zintoni iiizikrufu zedekhingokuchanekileyo, kwaye zahluke njani kwizikrufu zomthi?

Isishwankathelo seDekhi Screws

Izikrufu zedekhi ziziqhoboshi ezinemisonto eziyilelwe ngokukodwa iidekhi. Zibonisa incam, i-shank kunye nentloko. Ngaphakathi kwentloko kukho ikhefu lohlobo oluthile lwesuntswana, njengentwana yentloko kaPhilips. Nokuba kunjalo, izikrufu zedekhi zizibophelelo ezinemisonto ezisetyenziselwa ukwakha iidekhi.

Izikrweqe zeDekhi vs Izikrweqe zokhuni

Ngelixa zombini zisetyenziselwa ukufakwa kwemithi, izikrufu zedekhi kunye nezikrufu zokhuni azifani. Uninzi lwezikrufu zedekhi zine-shank enemisonto epheleleyo. Ngamanye amazwi, i-ridges yangaphandle yandisa yonke indlela ukusuka kwincam ukuya entloko. Izikrufu zokhuni ziyafumaneka kwiidizayini ezahlukeneyo. Ezinye izikrufu zokhuni zinohlobo olufanayo lwe-shank ene-threaded epheleleyo, kanti ezinye izikrufu zokhuni zine-shank enemisonto engaphelelanga.

Izikrufu zedekhi kunye nezikrufu zomthi nazo ziyafumaneka kwizinto ezahlukeneyo. Unokufumana izikrufu zokhuni kwizinto ezininzi ezahlukeneyo, kubandakanywa insimbi engenasici kunye ne-carbon steel. Izikrufu zedekhi, ngokuchaseneyo, zenziwe ngokuthe ngqo ngezinto ezichasene ne-corrosion. Ezinye izikrufu zedekhi zenziwe ngentsimbi engenasici. Intsimbi engatyiwa yintsimbi yintsimbi ekwaziyo ukumelana nomhlwa. Ezinye izikrufu zedekhi zenziwe ngobhedu. Ubhedu yintsimbi eyomeleleyo ebonisa iipropathi ezinganyangekiyo kwi-corrosion.

Ukuba uthelekisa isikrufu sedekhi kwisikrufu somthi, unokuqaphela ukuba yangaphambili inomsonto onzulu kunowokugqibela. Umphandle wokuthunga kwizikrufu zedekhi unzulu kunezikrufu zomthi. Umsonto onzulu uvumela izikrufu zedekhi ukuba zigrumbe kwiiplanga zokhuni zomgangatho.

Izinto ekufuneka uziqwalasele xa ukhetha izikrufu zeDekhi

Xa ukhetha izikrufu zedekhi, kufuneka uqwalasele uhlobo lokuqhuba. Uhlobo lokuqhuba luchongwa ngokuphuma kwentloko. Kuya kufuneka ukhethe izikrufu zedekhi kwizinto ezifanelekileyo. Njengoko bekutshiwo ngaphambili, ziqhelekile ukuba zenziwe ngezinto ezinganyangekiyo kwi-corrosion. Ukongeza kwi-corrosion resistance, nangona kunjalo, izinto ezenziwe ngazo kufuneka zomelele kwaye zomelele.

Ungalibali ukuqwalasela ubude xa ukhetha izikrufu zedekhi. Kufuneka zibe zide ngokwaneleyo ukuze zikhusele ngokupheleleyo iiplanga zokhuni. Kodwa izikrufu zedekhi akufuneki zibe zinde kangangokuba ziphume ngasemva kweeplanga zokhuni.
