Txoj kev no yog siv los tiv thaiv xeb, ua ntej txhua yam, cov khoom siv los ua screws kom tau raws li qhov xav tau. Piv txwv li, kev siv cov xov tooj ntawm cov khoom siv tiv thaiv corrosion-rau cov ntsia hlau tsim, tab sis qhov tseeb, los ntawm qhov kev lag luam pom, tshwj tsis yog muaj cov kev cai tshwj xeeb, txwv tsis pub siv cov qauv no rau kev siv los tiv thaiv xeb tsis yog ua tau tshwj xeeb. Lwm txoj hauv kev los tiv thaiv xeb yog los ntawm kev siv ib puag ncig kom tswj, tsuas yog hom no, yuav tsum siv screws hauv ib puag ncig.

Lwm qhov ob txoj hauv kev los tiv thaiv xeb ntawm tsheb screws yog qhov sib cuam tshuam ntawm cov khoom siv thiab ib puag ncig thiab kev txhim kho ntawm cov ntsia hlau qauv feem. Thawj txoj hauv kev no feem ntau yog qhov yuav tsum tau siv rau qee cov txheej txheej, tshwj xeeb yog qee txheej txheej tiv thaiv corrosion, tuaj yeem pab cov screws kom tiv thaiv xeb. Qhov txheej txheem thib ob kuj tseem siv ntau hom, los ntawm kev txhim kho nws cov qauv, feem ntau nws tuaj yeem txhim kho qhov sib tiv tauj ntawm cov ntsia hlau thiab sab nraud ib puag ncig, thiaj li ua tiav cov txheej txheem los tiv thaiv xeb.
