Cov ntsia hlau, cov fasteners feem ntau hauv lub neej niaj hnub, tau dhau ntau pua xyoo ntawm txoj kev loj hlob, thiab kev hloov pauv ntawm lawv lub taub hau tsim tau dhau los ua ib feem ntawm lawv keeb kwm. Los ntawm thawj qhov yooj yim slotted thiab Phillips taub hau screws mus rau niaj hnub no muaj ntau haiv neeg thiab tshwj xeeb tsim, kev hloov nyob rau hauv Screw Heads yog ze ze rau kev lag luam kev loj hlob, tshwj xeeb tshaj yog nyob rau hauv kev txhim kho kev nyab xeeb thiab anti-disassembly kev ua tau zoo.
Qhov ntxov tshaj plaws ntsia hlau taub hau tsim tuaj yeem taug qab ntau tshaj li ob txhiab xyoo, nrog rau ob qho tib si feem ntau yog slotted thiab Cross Head Screws. Thaum cov duab no yooj yim, lawv muaj qhov zoo thiab qhov tsis zoo. Slotted screws, vim lawv cov cheeb tsam me me, tau yooj yim puas thaum lub sij hawm nruj thiab tau maj mam phased tawm. Phillips Screws, ntawm qhov tod tes, ruaj khov dua vim lawv qhov chaw sib cuag loj dua. Cov qauv no tau siv dav hauv ntau yam khoom siv thiab tau tsim ua ntau yam hloov pauv. Niaj hnub no, Phillips lub taub hau ntsia hlau tsis yog tsuas yog ib qho ntawm cov qauv siv feem ntau, tab sis kuj tseem muaj cov kiv cua Phillips Pan Taub Hau Screws thiab Windmill Phillips taub hau screws, uas feem ntau yog siv rau hauv aerospace, tub rog, thiab lwm yam kev lag luam uas yuav tsum muaj siab torque.
Nrog rau kev nce qib ntawm kev lag luam thiab thev naus laus zis, kev tsim lub taub hau tau dhau los ua ntau haiv neeg, tshwj xeeb tshaj yog nyob rau hauv cov teb uas xav tau siab precision thiab siab zog. Thaum xyoo pua 20th, Internal Square Screw tau tsim los ntawm Canadian engineer PL Robertson. Qhov kev tsim no ua rau Pan Lub Taub Hau Phillips Screw kev sib txuas muaj kev nyab xeeb dua thiab tau siv dav hauv kev tsim khoom. Tom qab ntawd, Hla Lub Taub Hau Screws nrog sab hauv hexagonal thiab sab hauv dodecagonal lub taub hau tsim tau qhia, tshwj xeeb tshaj yog ua tau zoo hauv siab - kev sib txuas torque. Lub caij no, tshwj xeeb tsim cov ntsia hlau xws li sab hauv daim duab peb sab thiab sab hauv Torx screws pib siv rau hauv cov khoom tshwj xeeb thiab ib puag ncig, tshwj xeeb hauv cov menyuam yaus cov khoom ua si thiab cov khoom siv hluav taws xob, los txhim kho tamper tsis kam.
Qhov tshwm sim ntawm Tamper-Cov Ntawv Pov Thawj Screws, tshwj xeeb tshaj yog nyob rau hauv lub hnub qub pentagonal tsim siv los ntawm cov hom xws li Apple, ntxiv txhim kho Grub Screw kev ruaj ntseg. Cov yam ntxwv tseem ceeb ntawm Set Screw yog tias nws tsuas tuaj yeem raug tshem tawm nrog lub hau ntswj tshwj xeeb, tiv thaiv kom tsis txhob raug tso cai. Txawm li cas los xij, nrog kev txhim kho thev naus laus zis, lwm cov cuab yeej tau tshwm sim, txo qhov ua tau zoo ntawm cov Tamper no -Cov Ntawv Pov Thawj Screws, tshwj xeeb tshaj yog nrog kev siv cov cuab yeej tsis yog- qub, ua rau lawv tsis muaj zog - pov thawj qhov tseem ceeb. Txawm li cas los xij, Stainless Steel Lag Screws tseem siv dav hauv cov khoom siv xws li xov tooj ntawm tes, khoos phis tawj, thiab tshuab plaub hau, tshwj xeeb hauv cov khoom siv hluav taws xob thiab cov ntawv thov uas muaj kev nyab xeeb siab.
Dhau li ntawm kev hloov pauv hauv cov qauv sab hauv, cov duab sab nraud ntawm lub taub hau kuj tseem hloov zuj zus mus. Piv txwv li, cov qauv tsim xws li sab nraud square, sab nraud hexagonal, thiab sab nraud pentagonal taub hau muaj zog dua torque thiab kev ua kom nruj, ua rau lawv tshwj xeeb tshaj yog haum rau cov ntawv thov kom muaj zog ntau dua qhov chaw thov. Sab Nraud Pentagonal Head Screws feem ntau pom muaj nyob rau hauv cov cheeb tsam tshwj xeeb xws li cov ntsuas dej npog, roj li qub, cov khoom siv hluav taws xob, thiab cov hluav taws tua hluav taws, tiv thaiv kev sib tsoo nrog cov cuab yeej siv. Sab nraud dodecagonal bolts feem ntau yog siv rau hauv siab -xav tau kev lag luam xws li aerospace, feem ntau siv siab- cov ntaub ntawv muaj zog xws li titanium lossis npib tsib xee alloys.
Nrog rau kev nce qib ntawm kev lag luam tas mus li, cov ntawv thov ntawm cov ntsia hlau tau dhau los ua ntau dua, thiab cov qauv tsim lub taub hau tau hloov zuj zus mus rau lub zog siab dua, miniaturization, thiab tiv thaiv - cov yam ntxwv disassembly. Hom thiab kev ua haujlwm ntawm niaj hnubntsia hlau taub hauua tau raws li qhov xav tau ntawm ntau qhov chaw, los ntawm cov khoom siv niaj hnub mus rau siab - cov tshuab precision; M4 Screws tau dhau los ua cov khoom tseem ceeb. Tsav los ntawm qhov sib txawv me me hauv cov khoom siv hluav taws xob, Micro-Screws xws li Y-Screws thiab Peb-Wing Screws tau tshwm sim. Cov me me -Diameter Screws, feem ntau tsuas yog 0.8 txog 3.2 hli, yog siv dav hauv cov khoom siv hluav taws xob precision.
Niaj hnub no, screws tsis yog yooj yim fastening cov cuab yeej; lawv lub taub hau tsim tau dhau los ua ib qho kev kawm txuas ntxiv rau cov engineers. Txhawm rau ua kom tau raws li cov qauv kev lag luam siab dua thiab xav tau kev thov ntau ntxiv, bolt tsim tau tawg tas li los ntawm cov kev txwv, muab cov kev daws teeb meem zoo dua thiab txhim khu kev qha. Txawm hais tias nws tiv thaiv kev sib tsoo, nce torque, lossis miniaturization, evolution ntawm bolts qhia txog kev nce qib hauv kev lag luam thiab thev naus laus zis. Los ntawm cov qauv yooj yim ib txwm siv rau niaj hnub no cov ntaub ntawv sib txawv, qhov kev hloov tshiab tas li hauv lub taub hau tau tsav txoj kev loj hlob ntawm kev tsim vaj tsev niaj hnub.
