Khoom ntawm 8.8 Qib Bolts Standard Rau 8.8 Qib Bolts

Tsis muaj kev cai tshwj xeeb rau cov khoom siv ntawmqib 8.8 bolts, tsuas yog qhov tso cai ntau ntawm cov tshuaj muaj pes tsawg leeg tau teev tseg. Ntev npaum li cov khoom ua tau raws li qhov yuav tsum tau muaj nyob rau hauv qhov kev teev tseg no, nws tuaj yeem siv los ua cov khoom siv rau qib 8.8muaj zog bolts. Txawm li cas los xij, ntau tus kws tshaj lij tseem xav txog tus qauv rau qib 8.8 bolts yog qhov tseem ceeb rau kev xaiv cov khoom siv.

Yuav kom ua tau raws li qhov yuav tsum tau ua ntawm 8.8 qib bolts nrog cov kev xav tau sib txawv, cov khoom siv yuav tsum tau txais kev kho cua sov tshwj xeeb kom ua tiav cov yam ntxwv hauv qab no:

1. Lub nominal tensile lub zog ntawm cov khoom siv ntsia liaj qhov rooj nce mus txog 640MPa qib;

2. Lub zog piv ntawm cov khoom siv ntsia liaj qhov rooj yog 0.8;

3. Lub nominal yield zog ntawm bolt khoom ncav cuag 640 × 0.8=800MPa qib;

4. Thaum xaiv cov khoom siv,qib 8.8 hexagonal boltstuaj yeem siv cov ntaub ntawv xws li 1035ACR (rau M10 thiab hauv qab) thiab 1040ACR (rau M12 thiab siab dua), CH38F, 1045ACR, 1039, 10B21, 10B33, 10B38, thiab lwm yam;

5. 8.8 qib hexagonal bolts siv tau cov ntaub ntawv xws li CH38F, 1039, 10B21 (rau M10-M12), 10B33 (rau M14), 10B38 (rau M12-M24), 1035ACR (rau M10 hauv qab no ), thiab 1040ACR (rau M12 saum toj no);

6. Cov ntsiab lus disc siv hauv cov khoom siv carbon steel tuaj yeem xaiv raws li cov khoom sib txawv. Piv txwv li, 4.8 qib hexagonal bolts tuaj yeem ua los ntawm cov ntaub ntawv xws li 1008K, 1010, thiab 1015K, 6.8 qib hexagonal bolts tuaj yeem ua los ntawm cov ntaub ntawv xws li 1032, 1035, 1040, CH38F, thiab 10839, qib.hexagonal boltstuaj yeem ua los ntawm cov ntaub ntawv xws li 1035ACR (rau M10 thiab hauv qab) thiab 1040ACR (rau M12 thiab siab dua), CH38F, 1045ACR, 1039, 10B21, 10B33, thiab 10B38, thiab 8.8 qib sab hauv hexagonal ntawm 8F cov ntaub ntawv tuaj yeem ua tau. , 1039, 10B21 (rau M10-M12 thiab siab dua), thiab 10B38. Cov ntaub ntawv xws li B33 (rau M14), 10B38 (rau M12-M24), 1035ACR (rau M10 hauv qab), thiab 1040ACR (rau M12 saum toj no) tuaj yeem siv rau qib 10.9 hexagonal bolts. Cov ntaub ntawv xws li 1045ACR thiab 10B38 tuaj yeem siv rau qib 8 thiab siab dua cov txiv ntoo. Cov ntaub ntawv xws li 1015 (M<16) and CH38F (M ≥ 16) can be used for grade 10 nuts. Materials such as CH38F, 1039, 10B21, and 10B33 can be used for grade 12 nuts. Materials such as 1039, 10B21, 10B33, and 10B38 can be used for carriage screws. 1015 and other materials can be used for hexagonal protruding bolts, CH38F, 1039, 10B21, 10B33, 10B38 and other materials can be used. Hexagonal wood screws can be made of 1008K, 1010 and other materials, including self tapping nails, wall panel nails, drill tail nails, etc Plywood nails can be made of materials such as 1018, 1022, CH22A, etc.

Muaj kev nkag siab zoo txog cov khoom siv thiab kev ua haujlwm ntawm qib 8.8boltstuaj yeem pab koj xaiv cov khoom tsim nyog kom tau raws li koj qhov kev xav tau engineering.
