Standard rau bolts threads

Muaj ntau yam qauv rauntsia liaj qhov roojthreads, nrog rau cov hauv qab no:

1.Metric Xov: Metric threads tau muab faib ua cov xov ntxhib thiab cov xov zoo, nrog cov qauv zoo xws li ISO 68-1 thiab ISO 965-1.

ISO 965-1 yog cov qauv xov tsim los ntawm International Organization for Standardization rau tsim thiab specification ntawm metric threads.Tus qauv no qhia txog qhov tsis xws li qhov ntev, qhov siab ntev, thiab cov kaum sab xis rau metric threads.ISO 965-1 tus qauv feem ntau suav nrog cov ntsiab lus hauv qab no:

Dimensional specifications: ISO 965-1 tus qauv qhia txog txoj kab uas hla, suab, thiab lwm yam specifications rau metric coarse thiab zoo suab threads.Ntawm lawv, cov kev qhia tshwj xeeb ntawm cov xov ntxhib yog M1.6 txog M64, thiab qhov tshwj xeeb ntawm cov xov zoo yog M2 txog M40.

Txoj cai kam rau ua thiab sib txawv: ISO 965-1 tus qauv txiav txim siab qhov kam rau ua thiab sib txawv ntawm cov xov los xyuas kom muaj kev sib hloov thiab kev ntseeg tau ntawm cov xov.

Lub kaum sab xis: ISO 965-1 tus qauv qhia lub kaum sab xis ntawm 60 degrees rau metric threads, uas kuj yog lub kaum sab xis tshaj plaws rau metric threads.

2.Unified Thread: Cov xov lus Askiv feem ntau siv hauv Tebchaws Meskas thiab qee lub tebchaws hauv tebchaws, nrog cov qauv zoo xws li UNC, UNF, UNEF, thiab lwm yam.

3.Pipe Thread: Cov yeeb nkab xov feem ntau yog siv rau kev sib txuas ntawm cov kav dej, nrog cov qauv zoo xws li NPT (National Pipe Thread) thiab BSPT (British Standard Pipe Thread), thiab lwm yam.

4.Special threads: Ntxiv nrog rau cov qauv xov uas tau hais los saum toj no, kuj tseem muaj qee cov qauv xov tshwj xeeb, xws li kais xov, daim duab peb sab xov, thiab lwm yam, tsim los rau cov ntawv thov tshwj xeeb.

Kev xaiv ntawm qhov raugntsia liaj qhov roojxov txheem yuav tsum tau txiav txim siab raws li cov kev cai siv tshwj xeeb thiab lub teb chaws / cheeb tsam cov qauv los xyuas kom meej tias cov bolts tuaj yeem raug siv thiab siv tau zoo rau cov khoom siv lossis cov qauv.
