Kev lag luam tsim ntau hom fasteners tsim rau ntau lub hom phiaj. Cov no yog cov ntsia hlau, bolts, ntsia hlau, thauj tog rau nkoj, ntsia hlau. Nws yog qhov kawg uas yuav tau tham txog. Cov ntsia hlau yog cov khoom sib txuas nrog lub taub hau zoo li lub khob hliav qab thiab cov hlua txuas nrog rau tag nrho qhov ntev. Nws yog siv los txuas ntau yam (ntoo, hlau, yas, thiab lwm yam). Lub qhov (socket) yuav tsum tau threaded. Ib qho hlais yog txiav rau hauv lub dav hlau ntawm lub taub hau rau screwing.

Qee zaum nws yuav tsum tau txuas cov khoom hauv txoj hauv kev uas lawv qhov chaw tsis muaj qhov cuam tshuam. Nyob rau hauv cov ntaub ntawv no, ib tug countersunk taub hau ntsia hlau yog siv: ruaj ntseg fastening ob qhov chaw, nws tseem tsis tau kiag li pom los ntawm sab nraud. Hauv cov tib neeg, feem ntau hu ua "sweat" ntsia hlau. Lub Phillips ntswj ntsia hlau yog siv los mount qhov txuas no. Tom qab kev teeb tsa hauv ib lub qhov threaded, cov ntsia hlau tau nruj rau sab xis.

Qhov mount no yog siv rau hauv ntau qhov kev lag luam: ntsuas ntsuas, tshuab engineering, nkoj tsim, vaj tsev thiab kev pabcuam hauv zej zog thiab lwm yamthaj chaw. Thiab nyob rau hauv kev tsim cov rooj tog, ib tug countersunk ntsia hlau yog tsuas yog ib tug indispensable khoom. Nrog nws, rooj, sideboards, txaj, txee thiab lwm yam khoom siv sab hauv yog qhov zoo nkauj thiab xis nyob. Feem ntau cov ntsia hlau no muaj qhov sib txawv ntxiv, piv txwv li, sab hauv hexagon, taw tes kawg rau tus kheej tapping, thiab lwm yam. Qhov no nthuav dav heev ntawm lawv daim ntawv thov.

Lub hexagon socket ntsia hlau yog qhov muaj txiaj ntsig nyob rau hauv cov xwm txheej uas nws tsim nyog los txuas thiab txiav cov ntu ntu. Nws txawv ntawm qhov ib txwm muaj los ntawm qhov muaj qhov tshwj xeeb-zoo li lub taub hau. Rau unscrewing thiab screwing, ib tug tshwj xeeb hex key yog muab tso rau hauv nws. Cov fasteners zoo li no muaj zog dua cov fasteners yooj yim, thiab tseem siv tau ntev dua. Cov slots ntawm ib tug pa ntsia hlau sai sai yuav siv tsis tau thaum feem ntau unscrewed, uas yeej tsis tshwm sim nrog ib tug hex groove.

Cov ntsia hlau countersunk tsis ua rau cov tsos ntawm cov khoom, thiab lub qhov (socket) ntsia hlau yog qhov txhim khu kev qha. Ob hom fastening yog nrov heev nyob rau hauv kev lag luam thiab nyob rau hauv lub neej txhua hnub. Los ntawm kev sib txuas cov kev ua tau zoo, cov ntsia hlau tau tsim ib txhij nrog lub taub hau countersunk thiab lub hauv siab hexagon. Siv lawv, lawv tau muaj zog heev, thiab tib lub sijhawm sib txuas tsis pom kev.

GOST rau bolts thiab screws tau sau tseg kom siv cov qib tshwj xeeb ntawm cov hlau rau lawv cov khoom siv, vim tias qhov zoo ntawm cov ntsiab lus no feem ntau cuam tshuam ncaj qha rau lub zog ntawm cov pob qij txha tseem ceeb. Piv txwv li, hauv kev tsim kho thiab kev siv tshuab engineering, kev nyab xeeb yuav nyob ntawm qhov kev ntseeg tau ntawm cov fasteners,txawm neeg lub neej.

Cov ntsia hlau thiab bolts tuaj yeem ua los ntawm tooj dag, tooj liab thiab txawm tias ntoo. Steel fasteners muaj ob qho tib si tsis muaj txheej thiab nrog nws. Raws li yav tas los, zinc dawb feem ntau siv.

Cov ntsia hlau countersunk yog ib qho tseem ceeb heev, thiab qee zaum tsuas yog hloov tsis tau. Tam sim no, tsis muaj cov qauv tsim nrog nws cov kev pab, nws tsis tuaj yeem xav txog yuav luag txhua qhov kev lag luam. Nws tsis tshua muaj siv nyob rau hauv lub neej txhua hnub, tso cai rau koj ua kom muaj zog heev, zais thiab zoo sib txuas.
