Ntau tus neeg pom tias thaum yuav lub hau ntswj, koj tuaj yeem tau txais ntau qhov ntxiv hauv cov khoom siv. Screwdriver khoom yog ib qho ntxiv rau cov khoom siv. Nws yog qhov zoo dua los nkag siab qhov no ua ntej thiab yuav khoom dab tsi yuav tsum tau ua thaum ua haujlwm. Tsis yog txhua leej txhua tus paub dab tsi ntswj ntsia hlau yog muag thiab lawv siv rau dab tsi.

Slotted

Bits muaj ntau qhov kev faib tawm. Tab sis txhua tus muaj nws tus kheej lub hom phiaj thiab cov peev txheej. Screwdrivers rau ib lub qhov ncaj tau paub rau cov kws ua haujlwm rau ntau xyoo. Muaj, ntsig txog, thiab cov khoom. Lawv tuaj nrog lub npe S. Tom qab ntawd, ib qho cim hauv daim ntawv ntawm tus lej ntxiv nyob ze ntawm tsab ntawv. Qhov no yog qhov dav ntawm lub hau ntswj me ntsis. Tseem muaj lwm yam ntxiv thiab. Txhua yam nyob ntawm tus neeg tsim khoom.

Cov ntsia hlau ntsia hlau tsis muaj tsawg nyob rau hauv kev thov hnub no dua li ua ntej. Yog hais tias peb tig mus rau classics, ces txhua leej txhua tus yuav pom lub npe ntawm qhov dav nyob rau hauv qhov ntau ntawm 3 mus rau 9 millimeters. Lub thickness tsis qhia, vim hais tias nws mus nyob rau hauv lub feem ntau lees paub qhov taw qhia txog 1.6hli. Tsis tas li ntawd, cov hom zoo li no yuav tsum muaj kev tiv thaiv ntxiv thiab ua haujlwm ntev. Cov kev xaiv tom ntej yog ib qho me me nrog titanium nitride. Nov yog hom kev pab them nqi kho mob. Ntxiv nrog rau kev tiv thaiv corrosion ntxiv, qhov dav nce mus rau 6.5 millimeters. Ntawm kev muag khoom, cov ntsiab lus ntxiv yog cim TIN. Lawv thickness ncav cuag 1.2 millimeters.

Screwdriver bits muaj lwm qhov zoo. Qhov no yog ib daim ntawv ntev dua, tsis muaj qhov nyuaj rau ua qee yam haujlwm. Cov no suav nrog cov txheej txheem hloov maj mam thiab meej. Xws li lub nozzle zaum nruj hauv lub hau. Qhov ntev tuaj yeem ncav cuag 10 centimeters. Nws yog ib qho nyuaj ua tsis muaj qee lub ntsiab lus thaum ua cov haujlwm yooj yim tshaj plaws. Yog li ntawd, txhua leej txhua tus tau sim kom tau txais ntau qhov sib txawv ntawm cov ntsia hlau ntsia hlau.

Cross bits

Nov yog lwm yam. Xws li cov khoom pib xav tau tsis ntev dhau los. Qhov no yog vim cov txheej txheem yuav tsis ua raws li txoj haujlwm. Lawv tsuas dhia tawm ntawm lub kaus mom. Raws li qhov tshwm sim, cov haujlwm ua haujlwm tsis zoo thiab siv sijhawm tsawg. Tab sis tom qab ib pliag, cov khoom yooj yim dua tau tsim. Hauv khw lawv tau sau npe RN. Txhua lub fastener muaj nws tus kheej xov, yog li tsis txhob yuam kev, muaj cov ntsuas digital. Muaj nuj nqis zoo li no:

  • 0-2 mm.
  • 1-3 mm.
  • 2-5 mm.
  • 3-7 mm.
  • 4-7.1 mm.

Muaj cov qauv me me uas feem ntau siv. Cov no suav nrog qhov ntsuas txog li 4 millimeters. Thiab ntawm no yog qhov loj tshaj plaws rauscrewdriver khoom yog 2 mm. Lawv feem ntau haum rau hauv cov txheej txheem ntawm kev ua haujlwm hauv tsev. Thiab hauv kev tsim khoom, craftsmen siv 3 thiab 4 millimeters kom ntau dua.

Qhov zoo tshaj plaws yog qhov sib dhos zoo li tus laum me ntsis. Lawv tau siv ntau zaus, yog li muaj ntau lub tuam txhab ua lag luam uas tau npaj los muab cov qauv zoo li no. Thaum muas, koj yuav tsum tau them sai sai rau cov txheej txheej ntxiv uas tuaj yeem ua rau lub neej ntawm me ntsis. Hauv khw muag khoom kho vajtse, koj tuaj yeem ua tau raws li cov ntawv luv luv hauv qab no:

  • PH – 1.
  • PH – 2.
  • PH – 3.
  • dab tsi ntawm cov ntsia hlau ntsia hlau
    dab tsi ntawm cov ntsia hlau ntsia hlau

Ntau zaus hauv cov txheej txheem ua haujlwm, cov xwm txheej yuav tshwm sim thaum nws nyuaj rau kev nkag mus rau cov fasteners. Rau qhov no, elongated ntoo khaub lig-puab khoom yog muag. Yog li ntawd, ib qho (txawm tias ib qho qub fastener) yog unscrewed sai sai thiab tsis muaj teeb meem. Muaj tus qauv loj. Qhov ntev tuaj yeem ncav cuag 150 millimeters.

Pozidriv - PZ, qhov no yog lwm qhov cim ntawm kev muag khoom. Lawv yog cov zoo meej rau woodworking. Masters nyiam muab lawv thaum ua haujlwm nrog rooj tog. Muaj qhov sib txawv, thiab lawv tau qhia raws li hauv qab no:

  • Cov npoo ntawm qhov chaw ua haujlwm yog sib npaug.
  • Ib thickness tag nrho txoj kev.
  • qhov tob tob.

Thaum cov txheej txheem ntawm screwing nyob rau hauv ib lub fastener pib, lub cuab tam mus nruj, tom qab uas lub siab tshaj plaws kev tiv thaiv yog tsim. Qhov no yog ib qho zoo me ntsis rau lub hau ntswj, uas koj tsis tuaj yeem ua yam tsis muaj kev ua liaj ua teb. Tab sis thaum tsim ib tus kheej assortment, nws yog tsim nyog xav txog qhov yuav tsum tau rau ib tug los yoglwm yam. Tsis tas yuav sau cov khoom uas tsis muaj txiaj ntsig hauv cov txheej txheem.

PZ and notches

Qee cov tuam txhab tsim cov ntawv sau rau lawv. Tab sis lawv yog dab tsi? Yog li, theem ntawm hnav yog txo. Mus rau lub khw muag khoom kho vajtse, koj tuaj yeem pom cov khoom nrog txheej ntxiv.
