Nta thiab Cov txiaj ntsig
DIN 6921 yog ib hom hex flange bolt uas feem ntau siv hauv kev lag luam thiab kev tsim kho.Cov ntsia liaj qhov rooj no muaj lub flange uas ua raws li lub tshuab ntxhua khaub ncaws thiab pab faib cov khoom hla ntawm thaj chaw dav dua.Lub taub hau ntawm lub ntsia liaj qhov rooj yog hexagonal nyob rau hauv cov duab thiab yog ib qho yooj yim rau zawm siv ib tug ciaj ntswj los yog lub qhov (socket).
Cov ntsia liaj qhov rooj no yog dav siv nyob rau hauv machinery, automotive industries, thiab nyob rau hauv kev tsim kho, vim nws tshwj xeeb zog thiab durability.Nws yog tsim los ntawm cov ntaub ntawv zoo xws li stainless hlau, titanium, thiab carbon hlau, uas muab lub sij hawm ntev tiv thaiv hnav, corrosion, thiab xeb.
DIN 6921 bolts yog tsim los rau nruj tolerances thiab yuav tsum nruj me ntsis tswj kev ntsuas kom ntseeg tau tias lawv ua tau raws li cov qauv siab tshaj plaws ntawm kev ua tau zoo thiab kev ua tau zoo.Cov bolts no muaj nyob rau hauv ntau qhov ntau thiab tsawg, qhov ntev, thiab ua tiav kom haum rau cov kev siv sib txawv thiab cov kev xav tau.
Tsis tas li ntawd, DIN 6921 bolts ua raws li cov qauv kev lag luam nruj, suav nrog DIN (Deutsches Institut für Normung) thiab ISO (International Organization for Standardization) cov qauv.Lawv kuj raug sim rau lawv qhov hardness, tensile lub zog, thiab qhov tseeb qhov tseeb ua ntej tso tawm rau kev muag khoom.Tag nrho cov xwm txheej no ua rau muaj txiaj ntsig zoo thiab txhim khu kev qha ntawm DIN 6921 bolt.
Zuag qhia tag nrho, DIN 6921 bolt yog ntau yam thiab muaj zog fastening tov uas yog siv nyob rau hauv ntau yam kev lag luam.Nws yog tsim los muab lub zog tuav zoo heev, tiv taus hnav thiab tsim kua muag, thiab yooj yim ntawm kev teeb tsa.Nws txoj kev tsim kho zoo thiab kev ua raws li cov qauv kev lag luam ua rau nws yog qhov kev xaiv zoo tshaj plaws rau engineers, designers, thiab cov kws tsim kho thoob ntiaj teb.
