Ukuqonda uKwahlula phakathi kokuZibetha kunye neZikrufu eziqhelekileyo

1. Iindidi zemisonto: I-Mechanical vs
Izikrufu ziza kwiintlobo ezimbini zemisonto yokuqala: oomatshini kunye nokuzicofa.Amazinyo omatshini, ahlala efinyeziwe ngokuthi "M" kwishishini, asetyenziselwa ukubetha amantongomane okanye imicu yangaphakathi.Ngokuqhelekileyo ngokuthe ngqo kunye nomsila osicaba, eyona njongo yabo iphambili kukuqinisa isinyithi okanye iindawo zomatshini zokukhusela.Kwelinye icala, izikrufu ezizibethayo zibonakalisa amazinyo anonxantathu okanye amise okwesangqa semixantathu.Eyaziwa ngokuba zizikrufu ezizitshixayo, uyilo lwazo lwentambo oluphuculweyo luvumela ukungena lula ngaphandle kokufuna umngxuma ogrunjwe kwangaphambili.

2. Uyilo lweNtloko kunye noMahluko weProfayili
Umahluko obalaseleyo phakathi kwe-self-tapping screws kunye ne-screws eqhelekileyo ilele kuyilo lwentloko kunye neprofayili yomsonto.Izikrufu eziqhelekileyo zinentloko ethe tyaba, ngelixa izikrufu zokuzicofa zinentloko etsolo.Ukongeza, i-diameter ye-self-tapping screws iguquka ngokuthe ngcembe ukusuka ekupheleni ukuya kwindawo eqhelekileyo yobubanzi, ngelixa izikrufu eziqhelekileyo zigcina i-diameter ehambelanayo, zihlala zine-chamfer encinci ekupheleni.

Ngaphezu koko, i-angle yeprofayili yezinyo idlala indima ebalulekileyo.Izikrufu eziqhelekileyo zine-engile yeprofayili yezinyo eyi-60°, inika amandla abalaseleyo okubambelela kunye nozinzo.Ngokwahlukileyo, izikrufu zokuzicofa zine-engile yeprofayili yezinyo engaphantsi kwe-60 °, ezenza ukuba zivelise imisonto yazo njengoko zigqobhoza izinto ezinje ngomthi, iplastiki, okanye iintsimbi ezibhityileyo.

3. Ukusebenziseka kunye neeNgqwalasela zokuSebenza
Umahluko phakathi kwe-self-tapping screws kunye nezikrufu eziqhelekileyo zimisela usetyenziso lwazo oluthile kunye nokuqwalaselwa kokusetyenziswa.Izikrufu eziqhelekileyo zidla ngokusetyenziswa kwiimeko apho ulungelelwaniso oluchanekileyo kunye nokuzinza kubalulekile, njengokuhlanganisa izixhobo zombane ezibuthathaka okanye ukukhusela izixhobo zoomatshini.

I-self-tapping screws, ngakolunye uhlangothi, zenzelwe ngokukodwa ukwenza imicu yazo yokukhwelana njengoko iqhutyelwa kwizinto ezithambileyo, zisusa imfuno yemingxuma esele igrunjwe ngaphambili.Basetyenziswa kakhulu kumsebenzi wokwenza amaplanga, ukuqhoboshela izinto ezithile kwi-drywall, ukudibanisa ifanitshala nokufakela amacangci okufulela.

Kubalulekile ukuqaphela ukuba i-self-tapping screws ayinakufaneleka kuzo zonke izicelo.Xa usebenza ngezinto ezinzima njengensimbi engenasici okanye i-alloys, imingxuma esele ifakwe ngaphambili isoloko iyimfuneko ukuze kuqinisekiswe ukufakwa ngempumelelo ngaphandle kokonakalisa isikrufu okanye izinto eziphathekayo.
