Ukuqaliswa kweentlobo ezahlukeneyo ze-self-tapping screws

I-self-tapping screw luhlobo lwe-screw esetyenziselwa ukudibanisa izinto zetsimbi kunye namacwecwe.Ineentlobo ezininzi, ezifana ne-self-tapping pin screw, i-wallboard self-tapping screw, i-self-tapping screw, intloko ye-pan kunye ne-hexagon head self-tapping screw, njl.Okulandelayo, siza kukwazisa ngokufutshane ezi.

1. I-self-tapping fastening screws nayo isetyenziselwa ukudibanisa iipleyiti zetsimbi ezincinci.Umtya ngumtya oqhelekileyo kunye necandelo likanxantathu we-arc, kunye nomgangatho ophezulu wentambo unomgangatho ophezulu wobunzima.Ngoko ke, ngexesha loxhulumaniso, i-screw ingaphinda icofe intambo yangaphakathi kumngxuma ongezantsi wentambo yecandelo elidibeneyo, ngaloo ndlela udala uxhumano.Olu hlobo lwe-screw lubonakaliswa nge-screw-in torque ephantsi kunye neempawu zokutshixa eziphezulu.Ineempawu zokusebenza ezingcono kunezikrufu eziqhelekileyo zokuzicofa kwaye zinokusetyenziswa endaweni yezikrufu zomatshini.

2. I-screw panel yodonga lwe-self-tapping screw isetyenziselwa ukudibanisa phakathi kwendawo yodonga lwe-gypsum kunye ne-keel yensimbi.Umsonto unentloko ephindwe kabini, kwaye umaleko womphezulu wentambo nawo unomgangatho wobulukhuni obuphezulu (≥ HRC53), onokukhawuleza ujikwe kwi-keel ngaphandle kokwenza imingxuma esele yenziwe ngaphambili, ngaloo ndlela udala unxibelelwano.

3. Umahluko phakathi kwe-self-drilling self-tapping screw kunye ne-self-tapping screw ngokubanzi kukuba ukudityaniswa kwe-self-tapping screw jikelele kufuneka kuhambe ngeendlela ezimbini: ukugaya (ukubhobhoza umngxuma ongezantsi) kunye nokucofa (kubandakanya ukudibanisa ukudibanisa);Xa i-self-drilling self-tapping screw ixhunyiwe, iinkqubo ezimbini zokugaya kunye nokubetha zidibene.Iqala isebenzisa i-drill bit phambi kwe-screw ukugqiba u-drilling, kwaye isebenzisa isikrufu ukugqiba ukucofa (kubandakanya uxhulumaniso olukhawulezayo), olugcina ixesha lokwakha kunye nokuphucula ukusebenza kakuhle kolwakhiwo.

4. I-Pan-head kunye ne-hexagon-head self-tapping screws zifaneleke ngakumbi kwiindawo apho i-drill bit ivunyelwe ukuba ibonakale.Izikrufu ze-hexagon-head self-tapping zinokuba netorque enkulu kune-pan-head self-tapping screws.I-countersunk head kunye nehexagon socket izikrufu zentloko yokucofa zifaneleke ngakumbi kwiindawo apho intloko yesijivu ingenako ukuvela.I-hexagon socket head izikrufu zokucofa zinokuthwala itorque eninzi kunezikrufu zokucofa zentloko ezishiyiweyo;Isikrufu se-semi-jun head self-tapping screw ifaneleke ngakumbi kwiindawo apho intloko ye-screw ivumelekile ukuba ivele kancinci.Xa udityaniswa kwaye uqhawula izikrufu ezizicofayo, izikrufu ezityibilikayo ezizicofayo ziya kusebenzisa izikrufu ezislotyolweyo, izikrufu ezizincamathelayo ezinqamlezileyo ziya kusebenzisa izikrufu ezimilise okwemilo enqamlezileyo, izikrufu ze-torx ezizicocayo ezihexagonal ziya kusebenzisa izikrufu ze-torx ezinehexagonal, kunye ne-self-tapping ene-hexagonal. izikrufu ziya kusebenzisa izikrufu eziqinileyo, iziklintshi zeringi, izikrufu zesokhethi okanye iziklintshi ezilungelelanisiweyo.
