Screw ke e 'ngoe ea li-fasteners tse tloaelehileng,' me ho na le mefuta e mengata ea li-screw, tse kenyeletsang li-drill tails le li-self tapping screws.
Mohatla oa sekoti sa mohatla oa boro o sebopehong sa mohatla oa ho phunya kapa mohatla o motsu, 'me ha o hloke ts'ebetso e thusang. E ka phunngoa ka ho toba, ea tekenoa, 'me ea notleloa holim'a lisebelisoa tsa ho seta le thepa ea motheo, ho boloka nako ea kaho haholo. Ha e bapisoa le li-screws tse tloaelehileng, e na le matla a phahameng a tsitsipano le matla a ho tšoara, 'me e ke ke ea lokoloha le ka mor'a ho kopanngoa nako e telele. Ho bonolo ho sebelisa ho cheka ho sireletsehileng le ho tlanya ho phethela ts'ebetso ka nako e le 'ngoe. Haholo-holo ho kopanngoa ha kaho, meaho, bolulo le libaka tse ling, li-self tapping le li-self-drilling screws ke li-fasteners tse molemo ka ho fetisisa tsa moruo mabapi le ts'ebetso, litšenyehelo le botšepehi.
Li-self tapping screws, tse tsejoang hape e le li-screws tse sebetsang ka potlako, ke li-fasteners tsa tšepe tse kentsoeng holim'a galvanization le passivation. Li-self tapping screws li atisa ho sebelisoa bakeng sa ho hokahanya lipoleiti tsa tšepe tse tšesaane (joaloka lipoleiti tsa tšepe, li-saha, joalo-joalo). Ha o hokela, etsa lesoba le tlase la khoele bakeng sa karolo e hokahantsoeng, ebe u fafalletsa "self tapping screw" lesobeng le tlase le khoele la karolo e hoketsoeng.
① Ho khetholla lipakeng tsa likurufu tsa mohatla le likurufu tsa ho itahlela ho ea ka lisebelisoa: likurufu tsa mohatla ke tsa mofuta oa sekurufu sa patsi, athe likurufu tsa self tapping ke tsa mofuta oa sekurufu sa ho itšebetsa.
② Ho khetholla pakeng tsa li-screws tsa mohatla le li-self tapping screws ho latela ts'ebeliso ea tsona: Likurufu tsa mohatla li sebelisoa haholo ho lokisa lithaele tsa tšepe tse mebala le lipoleiti tse tšesaane ka har'a meaho ea tšepe. Tšobotsi e kholo ke hore mohatla o sebopeho sa mohatla oa ho phunya kapa mohatla o motsu. Ha e sebelisoa, ha ho na tlhoko ea ts'ebetso e thusang, 'me ho cheka, ho tlanya, ho notlela, le lits'ebetso tse ling li ka phethoa ka kotloloho holim'a thepa ka nako e le ngoe, ho boloka nako ea ho kenya haholo. Li-Self tapping screws li thata haholo 'me li ka sebelisoa ho lisebelisoa tse thata haholo, joalo ka lipoleiti tsa tšepe. E na le torque e tlase e tiisang le ts'ebetso e phahameng ea ho notlela.
③ Ho khetholla lipakeng tsa likurufu tsa mohatla oa ho phunya le likurufu tsa "self tapping" ho latela ts'ebetso: Likurufu tsa "Drill tail" ke lisebelisoa tse sebelisang melao-motheo ea 'mele le ea lipalo ea ho potoloha ha selikalikoe le khohlano ea lintho ho tiisa likaroloana tsa lintho butle-butle. Li-Drill tail screws ke li-screw tse nang le lihlooho tsa "self tapping" qetellong ea screw. Li-self tapping screws li atisa ho sebelisoa bakeng sa ho hokahanya lipoleiti tsa tšepe tse tšesaane (joaloka lipoleiti tsa tšepe, li-saha, joalo-joalo). Ha o hokela, etsa lesoba le tlase la khoele bakeng sa karolo e hokahantsoeng, ebe u fafalletsa "self tapping screw" lesobeng le tlase le khoele la karolo e hoketsoeng.
