Yuav Tsum Paub Txog Fasteners - Bolts
Feb 14, 2023
(1) Tus qauv siv rau nti bolts yog ANSI / ASME B18.2.1, thiab tus qauv Japanese hais txog JIS B1180 (Webster's thread). Inch system hais txog BSW916 (Webster hniav).
①HEX MACHINE BOLT: tsis muaj lub tshuab ntxhua khaub ncaws, nrog cov nqaj kawg, ib nrab tus hniav hexagonal ntsia liaj qhov rooj;
②HEX TAP BOLT: tsis muaj ntxhua khaub ncaws, tsis muaj nqaj kawg, tag nrho cov hniav hexagonal ntsia liaj qhov rooj;
③HEX CAP SCREWS: Hexagon bolts nrog washers, beam kawg, thiab ib nrab hniav;
(2) Cov qauv siv rau metric bolts yog raws li hauv qab no, thiab lawv qhov sib txawv tau qhia hauv lub rooj:
02. Carriage screws / round head square neck bolts
Carriage screws / round taub hau square caj dab bolts (Carriage Bolts): ANSI / ASME B18.5; DIN603; ISO 8677; GB 12; GB 14
03. Hexagon socket bolt
Hexagon socket-head cap screws: DIN912; GB 70; ISO 4762; ANSI / ASME B18.3
04. Hex ntoo ntsia hlau
Hexagon Lub Taub Hau Screws: ANSI / ASME B18.2.1 DIN 571
05. Rooj tog screws
Rooj tog screws (Furniture screws): raws li cov neeg siv khoom
06. Hex flange bolts
Hexagon Flange Bolt (Hexagon Flange Bolt): IFI111; GB5787; TIAB SA 921
kev txheeb xyuas cov khoom
01. Daim duab ntawm txhua qhov ntawm lub ntsia liaj qhov rooj:
02. Kev txheeb xyuas ntawm bolts:
Kos npe, chav kawm ua haujlwm
01. Logo
Hexagon taub hau bolts thiab screws (xov txoj kab uas hla Ntau dua lossis sib npaug li 5 hli). Nws yog ib qho tsim nyog yuav tsum tau siv lub cim tsa los yog concave rau saum lub taub hau, los yog lub cim concave ntawm sab ntawm lub taub hau. Nrog rau qib kev ua tau zoo thiab lub Hoobkas qauv.
Cov pa roj carbon steel: Lub zog qib kev cim npe muaj ob tus lej sib cais los ntawm "·". Lub ntsiab lus ntawm tus lej ua ntej "·" hauv cov cim cim qhia tias lub zog tensile nominal, xws li "4" hauv qib 4.8 qhia 1/100 ntawm nominal tensile zog 400N / MM2.
Lub ntsiab lus ntawm "·" nyob rau hauv cov cim cim thiab tus lej tom qab qhov taw tes qhia tias qhov sib piv ntawm lub zog, uas yog, qhov sib piv ntawm qhov taw tes nominal yield los yog lub zog nominal yield rau lub zog nominal tensile. Piv txwv li, qhov taw tes tawm ntawm qib 4.8 cov khoom yog 320 N / mm2.
Lub zog qib cim ntawm cov khoom siv hlau tsis muaj steel muaj ob ntu sib cais los ntawm "—". Lub cim ua ntej "—" nyob rau hauv lub cim code qhia cov khoom. Xws li: A2, A4 thiab lwm yam cim "—" qhia lub zog, xws li: A2-70
02. Qib
Cov pa roj carbon steel: Cov qib kev ua haujlwm ntawm cov metric bolts tuaj yeem muab faib ua 10 qib kev ua haujlwm: 3.6, 4.6, 4.8, 5.6, 5.8, 6.8, 8.8, 9.8, 10.9, thiab 12.9. Stainless hlau muab faib ua peb pawg: 60,70,80 (austenite); 50,70,80,110 (martensite); 45,60 (ferrtenite).
