I-Hex Head Self Drilling Screw

Lezi izikulufo zokuzibhoboza zamathayela ensimbi anombala. Ziyingxenye yesigaba se-self - tapping screws. Imvamisa, amakhanda azo eza ngezindlela ezihlukene njenge-hexagonal kanye nesiphambano - ahlehlisiwe. Umsila we-screw rod ubukhali ngezintambo, futhi ezinye zinewasha evala uphawu ngaphansi kwekhanda, engathuthukisa ukusebenza kokungangeni kwamanzi. Ikakhulukazi zenziwe nge-carbon steel ene-galvanized treatment noma insimbi engagqwali, ehlinzeka ngokugqwala okuhle - ukuvimbela nokugqwala - amandla okumelana.

Ngokuyinhloko zisetshenziselwa ukufakwa nokulungiswa kombala wensimbi yensimbi ophahleni nezindonga. Bangakwazi ukubhoboza ngokuqondile futhi bafihle emakhasini ensimbi njengamapuleti ensimbi anombala. Ukwengeza, nazo ziyasebenza ekuxhumekeni kokukhanya - ama-gauge steel keels kanye nezinye izakhiwo ezihambisanayo zokwakha.

Okokuqala, thola indawo yokufaka kuthayela wensimbi wombala noma impahla yensimbi efanele. Bese, sebenzisa ithuluzi lamandla elifanelekile (elifana ne-drill engenazintambo) elifakwe kancane elifana nohlobo lwekhanda lesikulufa. Qondanisa isikulufu nendawo enqunyelwe ngaphambilini, qala ithuluzi lamandla, bese ushayela isikulufu kancane kancane kokubalulekile. Ithiphu yokuzibhoboza izongena ezintweni ngenkathi imicu ishumeka kancane kancane, izuze ukulungiswa okuqinile.
