Koj puas paub tias thawj zaug paub sau cia sivntsia hlautshwm sim thaum lub sij hawm ntawm ancient Greeks?Lawv siv cov ntsia hlau hauv cov khoom siv los nias txiv ntseej thiab txiv hmab txiv ntoo, ua pov thawj rau lawv qhov kev txawj ntse thiab kev muaj peev xwm.Txij thaum ntawd los, screws tau hloov zuj zus mus rau hauv ib qho tseem ceeb tshaj plaws thiab siv dav hauv cov khoom siv kho vajtse tsim niaj hnub no.
Fastener kho vajtse tau hloov zuj zus mus rau lub sijhawm, nrog rau ntau yam ntawm cov duab, qhov loj me, qauv, thiab cov ntaub ntawv muaj nyob hauv khw.Thaum xaiv ib lub fastener rau koj daim ntawv thov, ib qho tseem ceeb tshaj plaws yuav tsum tau xav txog yog hom lub taub hau lub hau yuav muaj.
Lub taub hau ntawm cov ntsia hlau yog qhov tseem ceeb rau ntau yam laj thawj.Nws txiav txim siab txoj kev tsav tsheb lossis tig lub hau, thiab nws kuj cuam tshuam rau kev zoo nkauj thiab kev ua haujlwm ntawm cov khoom kawg.Yog li ntawd, nkag siab txog ntau hom ntsia hlau taub hau thiab lawv cov txiaj ntsig zoo yog qhov tseem ceeb rau kev txiav txim siab xaiv.
Ib hom ntsia hlau taub hau feem ntau yog lub taub hau Phillips.Tsim nyob rau hauv 1930s los ntawm Henry F. Phillips, nws nta ib tug ntoo khaub lig-puab recess uas tso cai rau ib tug Phillips ntswj ntsia hlau rau kev ruaj ntseg.Nws txoj kev tsim ua kom muaj kev sib kis tau zoo dua qub, txo qhov kev pheej hmoo ntawm kev swb thiab ua kom muaj kev sib txuas zoo dua.Lub taub hau Phillips tau dhau los ua ntau yam hauv kev lag luam thiab kev siv hauv tsev.
Lwm nrov ntsia hlau taub hau yog lub taub hau flathead, tseem hu ua ib tug slotted ntsia hlau.Nws nta ib qho ncaj ncaj rau saum, ua kom nws tsav tau siv lub taub hau taub hau.Txawm hais tias nws yuav tsis muaj kev tuav zoo ib yam li lwm lub taub hau ntsia hlau, nws tseem siv dav hauv kev ua haujlwm ntoo, rooj tog zaum, thiab lwm yam kev siv ib txwm siv.Lub flathead's simplicity thiab affordability ua rau nws muaj koob meej txuas ntxiv mus.
Nyob rau lub sijhawm tsis ntev los no, Torx lub taub hau tau nce qhov chaw.Tsim los ntawm Camcar Textron lub tuam txhab hauv xyoo 1967, nws muaj lub hnub qub rau lub hnub qub zoo li so.Qhov kev tsim no muab kev txhim kho torque kis tau tus mob, txo qhov kev pheej hmoo ntawm stripping los yog camming tawm.Lub taub hau Torx feem ntau yog siv hauv kev lag luam uas yuav tsum tau siv cov ntaub ntawv meej thiab siab, xws li tsheb, hluav taws xob, thiab aerospace.
Rau cov ntawv thov uas qhov kev zoo nkauj yog qhov tseem ceeb, lub qhov (socket head cap screw) muaj qhov zoo nkauj thiab ntws tawm.Nws nta lub taub hau cylindrical nrog lub qhov (socket) sab hauv hex, tso cai rau nws kom tau tsav siv Allen ciaj ntswj lossis hex yuam sij.Lub qhov (socket head cap screw) feem ntau yog siv rau hauv cov tshuab, tsheb, thiab cov rooj tog zaum siab, qhov xav tau kom huv si thiab zoo nkauj.
Tshaj li cov kev xaiv nrov no, muaj ntau ntau lwm hom ntsia hlau taub hau muaj, txhua tus nrog lawv qhov tshwj xeeb zoo.Piv txwv li, lub square tsav, Pozidriv, thiab hexagonal taub hau feem ntau yog siv rau hauv kev lag luam tshwj xeeb lossis kev siv tshwj xeeb.
Hauv kev xaus, kev xaiv ntawm txoj cai fastener rau koj daim ntawv thov yuav tsum xav txog ntau yam, xws li qhov loj me, cov khoom siv, thiab style.Txawm li cas los xij, hom lub taub hau cov ntsia hlau yuav muaj qhov tseem ceeb tshaj plaws, vim nws txiav txim siab tsav tsheb thiab tuaj yeem cuam tshuam rau tag nrho cov kev ua tau zoo thiab cov tsos ntawm cov khoom kawg.Txawm hais tias koj xaiv rau qhov sim thiab qhov tseeb Phillips lub taub hau, lub taub hau ib txwm muaj, lossis qhov tseeb ntawm Torx lub taub hau, kev nkag siab txog ntau hom ntsia hlau taub hau yuav xyuas kom meej tias koj txiav txim siab paub thaum nws los xaiv lub zoo meej fastener rau koj xav tau.
