Cov kev txwv uas yuav tsum tau ntaus cim los piav cov fasteners yog: cov khoom lag luam (cov qauv), qhov tshwj xeeb, khoom siv, qib zog, kho saum npoo. piv txwv DIN912, M4-0.7x8, SCM435, 12.9, blackened.

1. Npe (cov qauv)

Nco tseg: Rau cov ntsia hlau uas tsis muaj tus qauv thiab tsis txheem, cov duab kos yuav tsum tau npaj.

Piv txwv li, DIN912, Suav lub npe yog: hexagonal lub tog raj kheej taub hau ntswj, qhov no yog lub npe khoom.

Txawm li cas los xij, qhov tseeb tshaj plaws mus kom ze, tseem yuav tsum hu rau tus qauv, vim hais tias GB70 yog tib lub npe;

Lub ntiaj teb' s cov qauv muaj feem ntau muaj: German Standard (DIN), Thoob Ntiaj Teb Txuj (ISO), Tuam Tshoj National Standard (GB), Asmeskas Txuj (ANSI), Nyiv Pooj (JIS).

2. Cov lus hais.

Cov ntsia hlau dav dav salutation yog cov qauv hniav npe taub. Cov. Cov. ntsia hlau ntev.

Hniav qhov chaw nyob hniav, feem ntau siv hauv metric: M2, M3, M4, M5, M6, M8, M10, M12, thiab lwm yam.

Feem ntau siv hauv Tebchaws Asmeskas yog: 4-40, 6-32, 8-32, 10-24, 1 / 4-20, 5 / 16-18, 3 / 8-16, 1 / 2-13, thiab lwm yam.

Cov ntsia hlau ntev, ntawm qhov tod tes, hais txog qhov ntev ntev ntawm cov khoom faus. Piv txwv: cov ntsia hlau ntswj ntsia nrog qhov ntev tag nrho, ib nrab ntawm lub ntswj ntsia hlau ntxiv rau qhov ntev ntawm ib nrab ntawm lub taub hau, thiab lub taub hau cylindrical ntsia hlau ntev tsis suav nrog lub taub hau loj. Xws li:

Rau cov specifications, tag nrho lub npe yog qhov zoo tshaj plaws rau ntxiv suab. Piv txwv li, M4-0.7x8, 4 ntiv tes taub yog 4 hli, 0.7 hais txog qhov kev ncua deb ntawm ob lub ncov yog 0.7 hli, 8 hais txog qhov ntev ntawm qhov faus kwv tij yog 8 hli.

Txhawm rau yooj yooj yim thiab tsis sau suab, peb vim ntxawv cov hniav kom txheem cov hniav vim lawv feem ntau; Cov metric no nkaus xwb, Tebchaws Asmeskas cov khoom lag luam lossis cim qhov deb.

Qhov ua kom pom tseeb ntawm no yog nyob ntawm qhov tshwj xeeb ntawm american screws, xws li 6-32 x 3/8, 6 yog sab nraud ntawm cov hniav, ze li 3.5 hli;

Nov yog ob daim qauv los khaws cia hauv siab: hniav sab hauv lub cheeb A? (Ax0.013 ntxiv rau 0.06) x25.4 (hli), 1 nti, 25.4 hli.

Ntawm cov no, 2 x 2.2mm, 4 x 2.9mm, 6 x 3.5mm, 8 x 4.2mm, 10 x 4.8mm yog cov ntaub ntawv kom nco qab. Tus naj npawb ntawm cov hniav sib haum rau lub screws ntawm txhua qhov kev qhia tshwj xeeb kuj yuav tsum muaj kev cim: 2 s-56, 4 s-40, 6 s-32, 8 s-32, 10 s-24, 1 / 4-20, 5/16 -18, 3 / 8-16, 1 / 2-13 (Tebchaws Asmeskas cov hniav).

Nco tseg: Tebchaws Asmeskas UNC cov hniav yog cov qauv hniav, UNF yog cov hniav zoo. Peb ua rau peb nchav nchav niav mus rau cov hniav.

3. Cov Khoom Siv.

Cov ntaub ntawv raws li cov kev txiav txim siab tshaj plaws yog: carbon hlau, stainless hlau, xeb tsis muaj hlau, tooj, txhuas thiab lwm yam.

Cov pa roj carbon steel tau muab faib ua cov pa roj carbon tsawg (piv txwv li C1008 / C1010 / C1015 / C1018 / C1022), carbon hlau nruab nrab (xws li C1035), carbon hlau siab (C1045 / C1050), txhuas hlau (SCM435 / 10B21 / 40Cr).

Cov Khoom Siv C1008 cov khoom siv tau ua si cov khoom zoo nkauj hauv qib, xws li 4.8 qib screws, cov khoom siv rau qib zoo tib yam; C1035 nrog 8.8 screws, C1045 / 10B21 / 40Cr nrog 10.9 screws, 40Cr / SCM435 nrog 12.9 screws.

Stainless hlau nrog SS302 / SS304 / SS316 yog qhov ntau tshaj plaws. Ntawm chav kawm, tam sim no kuj nrov ntau ntawm SS201 cov khoom lag luam, txawm tias qis dua cov ntsiab lus nickel cov khoom lag luam, peb hu ua cov khoom siv tsis muaj steel hlau;

4. Siv tshuaj ntau qib.

Lub zog qib qib mas hais txog cov roj carbon steel fasteners.

Cov qib nquag muaj zog ntawm carbon steel screws yog: 4.8, 5.8, 6.8, 8.8, 10.9 thiab 12.9. Cov txiv laum raug rau: 4, 6, 8, 10, 12.

Feem ntau, screws qis dua qib 8.8 yog hu ua screws zoo tib yam, thaum screws saum qib 8.8 (suav nrog 8,8 qib) yog qhov muaj zog loj dua cov ntsia hlau. Qhov sib txawv yog hais tias muaj zog siab screws yog raug rau kev kho cua sov.

5. Kho deg.

Kev kho saum npoo yog feem ntau txhawm rau txhim kho kev txhim kho corrosion, tab sis kuj yog ib feem ntawm cov xim, yog li feem ntau yog ua rau cov pa roj carbon steel cov khoom, feem ntau yuav tsum mus los ntawm kev kho saum npoo.

Cov txheej txheem kho saum npoo yog: blackening, galvanizing, tooj liab plating, nickel plating, chrome plating, nyiaj plating, kub plating, Dacro, kub-dip zinc, thiab lwm yam.

Muaj ntau hom galvanizing, xiav thiab dawb zinc, xiav zinc, dawb zinc, daj zinc, dub zinc, ntsuab zinc, thiab lwm yam, tab sis tseem muab faib ua kev tiv thaiv ib puag ncig thiab tsis muaj kev tiv thaiv ib puag ncig, txhua lub plating muaj ntau hom txheej tuab. kom tau raws li qhov sib txawv cov tshuaj tsuag ntsev sib tw tshuaj.
