Factory Manufacture Ntau Bolt Truck Parts Round Head Torsional Shear Bolts

(1) Logo. Hexagon bolts thiab screws (xov txoj kab uas hla ≥5mm). Yuav tsum muaj lub cim convex lossis concave rau saum lub taub hau lossis ib lub cim concave ntawm sab ntawm lub taub hau. Nrog rau qib kev ua tau zoo, lub Hoobkas qauv. Cov pa roj carbon steel: Lub zog qib cim cim muaj ob tus lej sib cais los ntawm "·". Tus lej ua ntej "·" hauv qhov cim cim qhia tias lub zog tensile nominal. Piv txwv li, "4" hauv qib 4.8 txhais tau tias 1/100 ntawm lub zog tensile nominal ntawm 400N / MM2. Lub ntsiab lus ntawm "·" thiab cov ntu digital tom qab lub teev nyob rau hauv cov cim cim qhia qhov sib piv ntawm cov txiaj ntsig, uas yog, qhov sib piv ntawm qhov taw qhia nominal yield los yog lub zog nominal yield rau lub zog tensile nominal. Piv txwv li, qhov taw tes tawm ntawm qib 4.8 cov khoom yog 320 N / mm2. Stainless hlau khoom lub zog qib qhab nia yog tsim los ntawm ob qhov sib cais los ntawm "-". Lub cim ua ntej "-" qhia cov khoom. Piv txwv li, A2 thiab A4 qhia lub zog tom qab a -, piv txwv li, A2-70

(2) Qib. Cov pa roj carbon steel: Metric bolt mechanical kev kawm qib tuaj yeem muab faib ua: 3.6, 4.6, 4.8, 5.6, 5.8, 6.8, 8.8, 9.8, 10.9, 12.9 tag nrho ntawm 10 qib kev ua haujlwm. Stainless hlau muab faib ua 60,70,80 (austenite); 50,70,80,110 (martensite); 45,60 (ferrite) class iii.
