Piav qhov txawv ntawm Ntoo Screws Thiab Self-tapping Screws

Ua ntej piav qhia txog qhov teeb meem no, dab tsi yuav tsum tau nkag siab yog tias cov fasteners tuaj yeem muab faib ua peb pawg raws li daim ntawv xov, cov xov sab nraud, cov xov sab hauv, thiab cov xov uas tsis yog xov, thaum ntoo screws thiabself-tapping screwsbelongs rau Externally threaded fasteners.

        A ntoo ntsia hlauyog cov ntsia hlau tshwj xeeb tsim los rau cov ntoo, uas tuaj yeem ntsia tau ncaj qha rau hauv cov khoom ntoo (los yog ib feem), thiab cov hlau (lossis tsis yog xim hlau) ib feem nrog lub qhov los ntawm lub qhov yog ruaj khov nrog cov khoom siv ntoo. Qhov kev sib txuas no yog ib qho kev sib txuas detachable. Muaj 7 yam ntawm lub teb chaws tus qauv ntoo screws, namely 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 countersunk taub hau ntoo Cov ntsia hlau Countersunk taub hau ntoo ntsia hlau thiab hexagonal taub hau ntoo ntsia hlau, ntawm cov ntoo khaub lig recessed ntoo ntsia hlau yog siv ntau dua, thiab ntawm cov ntoo khaub lig recessed ntoo screws, ntoo khaub lig recessed countersunk taub hau ntoo screws yog feem ntau siv.

Thaum ib tug ntoo ntsia hlau tau nkag mus rau hauv cov ntoo, nws tuaj yeem embedded zoo heev. 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 xav tau cov cuab yeej rau unscrew ntoo screws. Lwm qhov peb yuav tsum tau them sai sai rau yog tias cov ntoo ntsia hlau yuav tsum tau muab ntsia hlau nrog lub hau ntswj, thiab cov ntsia hlau ntoo tsis tuaj yeem yuam nrog rauj. Qhov no yuav yooj yim ua rau cov ntoo nyob ib ncig ntawm cov ntoo screws thiab kev sib txuas yuav tsis nruj. Cov ntsia hlau ntoo muaj peev xwm kho tau zoo dua li cov ntsia hlau, thiab lawv tuaj yeem raug tshem tawm thiab hloov pauv yam tsis muaj kev puas tsuaj rau cov ntoo saum npoo, yog li lawv siv tau yooj yim dua.

Cov xov ntawm tus kheej tapping ntsia hlau pas nrig yog ib qho tshwj xeeb ntawm tus kheej tapping ntsia hlau xov, uas feem ntau yog siv los txuas ob yam hlau nyias (steel phaj, saw board, thiab lwm yam). Raws li lub npe implies, tus kheej-tapping ntsia hlau tuaj yeem tapping los ntawm nws tus kheej, nws muaj zog hardness, thiab tuaj yeem ntsia tau ncaj qha rau hauv lub qhov ntawm cov khoom siv los tsim cov xov hauv cov khoom sib txuas.

Self-tapping screws tuaj yeem siv cov xov sab hauv ntawm lub cev hlau los tsim cov xov txuas thiab ua lub luag haujlwm fastening. Txawm li cas los xij, vim nws txoj kab uas hla ntawm lub hauv paus loj, thaum nws siv hauv cov khoom siv ntoo, kev txiav rau hauv cov ntoo yuav yog qhov ntiav, thiab vim yog cov xov me me, yuav 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 cov ntoo mounting qhov chaw, tshwj xeeb tshaj yog cov ntoo looser.

Cov saum toj no yog kev taw qhia ntawm ntoo screws thiab self-tapping screws. Kuv vam tias nws tuaj yeem pab koj kom paub qhov txawv ntawm cov ntoo screws thiab tus kheej tapping screws. Yooj yim muab, ntoo ntsia hlau threads yog ntxaum thiab ntau spaced dua li tus kheej tapping screws, tus kheej tapping screws yog ntse thiab tawv, thiab ntoo screws yog ntse thiab mos.
