Ama-Self Drilling Screw atholakala ezinhlobonhlobo zobude nobubanzi be-shank. Ububanzi buboniswa usayizi wezinombolo oqala ku-#6 kuye ku-#14, futhi #6 ibe mncane kakhulu futhi #14 ibe mkhulu kakhulu. I #8 kanye ne-#10 Self Drilling Screws yizona ezisetshenziswa kakhulu.

Usayizi wethiphu uqokwe ngevelu elingu-1 ukuya ku-5, okubonisa ukujiya kweshidi lensimbi isikulufu esingangena kuso — u-1 umele insimbi encane kakhulu futhi u-5 ugqinsise. Ithiphu elivamile le-Self Drilling Screw yizikulufu ze-Thread 3, 4 kanye nezi-5 zidume kakhulu kunoma imaphi amaphrojekthi asebenzisa izinsimbi eziwugqinsi.

Izikulufu ze-thread 1 zenzelwe izinhlelo zokusebenza zokufulela ngokuxhunywa kwensimbi kuya kokhuni. Lezi zikulufu zifaka i-drill bit encane kakhulu, okusho ukuthi zenza imbobo enobubanzi obuncane kakhulu kunaleyo yezintambo zangaphandle kuso sonke isikulufu. Ngembobo encane, imicu ingaluma into ukuze ibambe ngokuphephile.

I-Self Drilling Screw nazo zihlukaniswa ngohlobo lwekhanda. Kunezinhlobo ezimbili ezijwayelekile zamakhanda e-Self Drilling Screw:

• Ikhanda lewasha le-Hex: Ifaka iwasha eyakhelwe ngaphakathi ukuze isabalalise kangcono izisindo nemithwalo endaweni ebanzi. Lesi sitayela silungele amaphrojekthi ophahla kanye nezinye izinhlelo zokusebenza ezinzima.
• I-truss eguquliwe: Ifaka ikhanda ledome eliwusayizi oweqile kanye ne-flange ukuze kwakhiwe indawo enkulu ngaphansi kwekhanda ukuze kube nendawo enkulu yokuthwala.

Ngaphandle kwalokho, zonke ezinye izitayela zamakhanda kuzikulufu zokuzibhoboza ngokuvamile zine-Phillips drive, esiza ekushayeleni isikulufu siqonde. I-square drive iya ngokuya ifunwa, njengoba kancane mancane amathuba okuthi ishelele ngenkathi ushayela. I-Phillips pan-head Self Drilling Screws ilungele izinhlelo zokusebenza ezilula.

Olunye uhlobo oluvamile lwesikulufu isikulufu sekhanda eliyisicaba, esisetshenziswa uma udinga indawo eshaywayo. Izikulufo zokuzibhoboza ezinamaphiko — ziwukhuni oluhle kakhulu lwezikulufu zensimbi.

Sivame ukucelwa izikulufu zokuzibhoboza zensimbi engagqwali. Ayatholakala, kodwa amathiphu awawona angcono kakhulu okubhoboza insimbi engagqwali. Kuzinhlelo zokusebenza zensimbi engagqwali, siphakamisa izikulufo ze-bi-metal Self Drilling, lapho umzimba wesikulufu uyinsimbi engagqwali, kanye nethiphu wenziwe ngensimbi ye-carbon, evumela isikulufu ukubhoboza kunsimbi engagqwali kalula.

Kufanele futhi uhlole iwebhusayithi yethu ngezansi ukuze uthole ulwazi olwengeziwe oluzokusiza ukuthi unqume isikulufu esingcono kakhulu sephrojekthi yakho elandelayo.
