Cov fasteners tuaj yeem muab faib ua peb pawg raws li daim ntawv xov, cov xov sab nraud, cov xov sab hauv, cov xov tsis muaj xov, cov ntoo ntsia hlau thiab tus kheej tapping screws yog tag nrho cov xov sab nraud. Cov ntsia hlau ntoo yog ib hom ntsia hlau tshwj xeeb uas tsim los rau cov ntoo, uas tuaj yeem txuas ncaj qha mus rau hauv cov khoom ntoo (los yog ib feem) kom ceev cov hlau (lossis tsis yog xim hlau) nrog ib qho los ntawm qhov mus rau cov khoom ntoo. Qhov kev sib txuas no yog ib qho kev sib txuas detachable. Muaj 7 yam ntawm lub teb chaws tus qauv ntoo screws, uas yog slotted round taub hau ntoo screws, slotted countersunk taub hau ntoo screws, slotted semi-countersunk taub hau ntoo screws, cross-recessed round taub hau ntoo screws, cross-recessed countersunk taub hau ntoo screws, cross-recessed ib nrab lub taub hau ntoo screws. Countersunk taub hau ntoo ntsia hlau thiab hexagon taub hau ntoo ntsia hlau, ntawm cov ntoo hlais ntoo screws yog siv ntau dua, thiab ntoo khaub lig recessed countersunk taub hau ntoo screws yog cov siv dav tshaj plaws ntawm cov ntoo khaub lig recessed ntoo screws.
Thaum cov ntsia hlau ntoo nkag mus rau hauv cov ntoo, nws tuaj yeem muab khi ruaj khov rau hauv nws. Yog cov ntoo tsis lwj, nws tsis yooj yim rau peb rub tawm. Txawm hais tias koj rub nws tawm, nws yuav ua rau cov ntoo puas thiab coj tawm cov ntoo nyob ze. Yog li ntawd, peb yuav tsum tau siv cov cuab yeej los unscrew ntoo screws. Lwm qhov tseem ceeb uas peb yuav tsum tau ua tib zoo saib yog tias cov ntoo ntsia hlau yuav tsum tau muab ntsia hlau ntsia hlau ntsia hlau, thiab cov ntsia hlau ntoo tsis tuaj yeem raug quab yuam nrog rauj, uas yuav yooj yim ua rau cov ntoo nyob ib ncig ntawm cov ntoo screws thiab kev sib txuas tsis nruj. . Lub peev xwm ua kom muaj peev xwm ntawm cov ntsia hlau ntoo muaj zog dua li cov ntsia hlau, thiab lawv tuaj yeem raug tshem tawm thiab hloov pauv, uas tsis ua rau cov ntoo nto thiab yooj yim dua rau siv. Cov xov ntawm tus kheej tapping ntsia hlau ntsia hlau yog ib qho tshwj xeeb ntawm tus kheej tapping ntsia hlau xov, uas feem ntau yog siv los txuas ob yam hlau nyias (steel plates, saw boards, thiab lwm yam). Raws li lub npe qhia, tus kheej-tapping ntsia hlau tuaj yeem ua tus kheej tapping, nws muaj zog hardness, thiab tuaj yeem ntsia tau ncaj qha rau hauv lub qhov ntawm cov khoom, kom cov xov sab hauv yog tsim nyob rau hauv cov khoom.
Tus kheej-tapping ntsia hlau tuaj yeem coj mus rhaub cov xov sab hauv ntawm lub cev hlau los tsim cov xov sib txuas thiab ua lub luag haujlwm nruj. Txawm li cas los xij, vim nws cov xov hauv qab txoj kab uas hla siab, thaum nws siv rau hauv cov khoom ntoo, qhov txiav rau hauv cov ntoo yuav ntiav ntiav, thiab vim yog cov xov me me, muaj cov qauv ntoo tsawg dua ntawm txhua ob txoj xov. Yog li ntawd, nws tsis muaj kev ntseeg siab thiab tsis muaj kev nyab xeeb los siv tus kheej tapping screws rau ntoo mountings, tshwj xeeb tshaj yog xoob ntoo. Cov saum toj no yog kev taw qhia ntawm ntoo screws thiab self-tapping screws. Kuv vam tias nws tuaj yeem pab koj paub qhov txawv ntawm cov ntoo ntsia hlau thiab tus kheej tapping screws. Hauv cov ntsiab lus yooj yim, ntoo ntsia hlau muaj cov xov sib sib zog nqus dua li tus kheej tapping screws, thiab qhov sib nrug ntawm cov xov kuj ntau dua. Self-tapping screws yog ntse thiab tawv, thiab ntoo screws yog ntse thiab mos.
