Vim hais tias muaj ntau hom screws, qhov kev ua tau zoo ntawm txhua tus ntawm cov screws yog txawv, yog li cov screws muaj sib txawv siv. Yuav kom tsis txhob siv qhov tsis ncaj ncees ntawm screws, peb yuav tsum muaj ib qho kev nkag siab ntawm kev ua tiav ntawm kev ntsuas, kom peb siv tau cov ciaj nyob rau hauv feem ntau yog qhov chaw. Ua ntej tshaj plaws, cia wb mus saib tus kheej-tapping screws, uas muaj qhov tapping self-tilt nrog ib lub cheeb ntawm 0.8 hli mus rau 12mm. Rau cov hom screws, lawv yog feem ntau ntawm kev kub ntxhov. Lub cav ntaiv nws tus kheej yuav tsum tau muab ntsia hlau rau hauv cov ntawv xeem, thiab cov ntsuas tau screwed rau hauv ib qho kev xeem. Tom qab ntawd qhov nyuaj ntawm lub screws yog soj ntsuam kom ua tau raws li tus qauv. Yog tias nws tsis yog tus qauv, nws xav tau kev soj ntsuam. Qhov teeb meem nyob qhov twg? Yog li nrhiav kev daws. Lwm hom yog cov ntsia hlau ntsia hlau. Raws li lub npe siv tau, tus Tsov tus tw ntawm qhov ntsia hlau yog feem ntau nyob rau hauv cov duab ntawm ib tus tail laum. Lub hardness ntawm no ntsia hlau yog tseem muaj zog heev. Piv nrog cov quas tsis zoo, nws tsis yog tsuas yog zoo dua los tswj, tab sis kuj nyob hauv cov khoom sib txuas. Cov nyhuv tseem muaj zog heev. Rau hom kev ua tau zoo no, feem ntau qhov kev ntsuas tsis xav tau kev pab cuam. Koj tuaj yeem ncaj nraim hnia ib lub qhov khoom rau ntawm tus kwv, uas yog tsis tsuas yog yooj yim siv, tab sis kuj zoo heev ua rau kev ua haujlwm. zoo heev. Hom kev drilling no yog thawj qhov kev xaiv rau cov neeg ua haujlwm nyob rau ntau thaj chaw.
Los ntawm cov saum toj no peb tuaj yeem pom tau tias peb paub qhov kev ua tiav ntawm ntau yam khoom siv thaum siv screws.
