Bolts, mechanical qhov chaw, cylindrical threaded fasteners nrog ceev. Bolt: Ib hom fastener uas muaj ob qhov chaw, lub taub hau thiab lub hau ntswj (lub tog raj kheej nrog cov xov sab nraud), uas yuav tsum tau muab sib xyaw nrog cov txiv ntseej kom ceev thiab txuas ob feem nrog los ntawm qhov. Daim ntawv no yog hu ua bolted kev twb kev txuas. Yog hais tias cov txiv ntseej yog unscrewed los ntawm lub bolt, ob qhov chaw tuaj yeem sib cais, yog li kev sib txuas bolted yog ib qho kev sib txuas uas tshem tau.
Raws li lub zog hom ntawm kev sib txuas: zoo tib yam thiab hinged qhov. Raws li cov duab ntawm lub taub hau: hexagonal taub hau, puag ncig lub taub hau, square taub hau, lub taub hau sunken thiab hais txog. Ntawm lawv, lub taub hau hexagonal yog feem ntau siv. Feem ntau, countersunks yog siv qhov twg yuav tsum muaj kev sib txuas.
Daim ntawv thov yog dav heev.
Muaj ntau lub npe rau bolts, thiab txhua tus neeg lub npe yuav txawv, qee tus neeg hu lawv cov ntsia hlau, qee cov neeg hu lawv cov ntsia hlau ntsia hlau, qee cov neeg hu lawv cov qauv, thiab qee cov neeg hu lawv cov ntsia hlau. Txawm hais tias muaj ntau lub npe, lub ntsiab lus yog tib yam, tag nrho cov bolts. Bolts yog lub ntsiab lus dav dav rau fasteners. Lub hauv paus ntsiab lus ntawm bolting yog ib qho cuab yeej uas siv lub cev thiab lej cov ntsiab lus ntawm inclined ncig rotation thiab kev sib txhuam ntawm cov khoom kom maj mam zawm cov khoom siv ntawm cov khoom.
Bolts yog qhov tseem ceeb hauv lub neej niaj hnub thiab kev tsim khoom lag luam, thiab bolts tseem hu ua industrial meters. Nws tuaj yeem pom tias bolts tau siv dav. Daim ntawv thov ntawm bolts suav nrog: cov khoom siv hluav taws xob, cov khoom siv kho tshuab, cov khoom siv digital, cov khoom siv hluav taws xob, cov khoom siv hluav taws xob electromechanical. Bolts yog siv hauv nkoj, tsheb, hydraulic engineering, thiab txawm tias kev sim tshuaj. Txawm li cas los xij, bolts tau siv ntau qhov chaw. Ib yam li cov precision bolts siv hauv cov khoom lag luam digital. DVDs, me me bolts siv nyob rau hauv lub koob yees duab, tsom iav, moos, electronics, thiab lwm yam.; General bolts rau TV, khoom siv hluav taws xob, cov twj paj nruag, rooj tog zaum, thiab lwm yam.; Raws li rau engineering, kev tsim kho, thiab txuas hniav, cov bolts loj thiab ceev yog siv; Cov khoom siv thauj mus los, dav hlau, tsheb ciav hlau, tsheb, thiab lwm yam yog siv ua ke rau cov bolts loj thiab me. Bolts muaj cov haujlwm tseem ceeb hauv kev lag luam, thiab ntev npaum li kev lag luam muaj nyob hauv lub ntiaj teb, kev ua haujlwm ntawm bolts yuav yog ib qho tseem ceeb.
