Hexagon socket bolts, tseem hu ua hexagon socket head cap screws, yog cylindrical fasteners nrog lub taub hau sab hauv hexagon tsav. Cov qib siv feem ntau ntawm hexagon socket bolts suav nrog 4.8, 8.8, 10.9 thiab 12.9. Cov kev ua haujlwm sib txawv thiab cov cuab yeej siv hauv tsev yuav tsum tau bolts ntawm cov qib sib txawv. Xaiv cov qib tsim nyog tuaj yeem muab kev ua si tag nrho rau kev ua haujlwm ntawm cov khoom siv fasteners thiab ua kom lub zog tag nrho ntawm kev sib dhos thiab kev nyab xeeb ntawm cov khoom siv.
1. Lub zog Qib Classification ntawmHexagon Socket Bolts
Hexagon socket bolts raug cais raws li cov ntsuas ntsuas xws li cov khoom siv hardness, tensile zog thiab lub zog tawm los hloov mus rau qhov sib txawv load. Hauv kev lag luam, lawv tau muab faib ua qhov zoo tib yam - zog thiab siab - qib zog. Qib 4.8 belongs rau qhov zoo tib yam hexagon socket bolts, thaum qib 8.8, 10.9 thiab 12.9 txhais tau tias siab -lub zog hexagon socket bolts. Standard Qib 12.9 bolts feem ntau yog dub-tiav nrog knurled hau thiab oiled nto.
Hexagon socket bolts siv rau cov qauv hlau thiab cov khoom siv sib dhos npog ntau qib kev ua tau zoo suav nrog 3.6, 4.6, 4.8, 5.6, 6.8, 8.8, 9.8, 10.9 thiab 12.9. Bolts ntawm Qib 8.8 thiab siab dua yog tsim los ntawm nruab nrab- carbon steel los yog qis- alloy steel thiab raug quenching thiab tempering kub kho los txhim kho cov khoom siv kho tshuab, uas txhais tau tias siab - lub zog bolts. Tag nrho lwm yam uas tsis yog{14}} cua sov- kho qis- qib bolts raug cais raws li cov bolts zoo tib yam.
Cov qhab nia qib kev ua tau zoo muaj ob pawg ntawm tus lej, sawv cev rau lub zog tensile nominal thiab cov txiaj ntsig ntawm cov khoom siv ntsia liaj qhov rooj. Qhov no yog ib qho kev sib koom ua ke thoob ntiaj teb tus qauv. Bolts nrog tib qib kev ua tau zoo qhia tau zoo ib yam khoom siv tsis hais cov khoom sib txawv lossis kev tsim khoom, yog li kev tsim qauv engineering tuaj yeem ua tiav raws li qib zog.
2. Mechanical Properties ntawm Txhua Bolt Qib
Qib 4.6 Bolt Performance: Lub nominal tensile lub zog yog 400 MPa, yield ratio yog 0.6, thiab lub nominal yield zog yog 240 MPa.
Qib 10.9 Siab -Strength BoltKev ua tau zoo: Tom qab kev kho cua sov, lub nominal tensile zog ncav cuag 1000 MPa nrog ib tug yield ratio ntawm 0.9, thiab lub nominal yield zog mus txog 900 MPa.
Cov qib sib txawv ntawm lub zog sib txawv ntawm cov khoom siv raw, cov txheej txheem ua haujlwm thiab cov txheej txheem kho cua sov, nrog rau cov nqi nce ntxiv. Hauv cov ntawv thov kev lag luam, Qib 4.8, 8.8, 10.9 thiab 12.9 hexagon socket bolts yog qhov siv dav tshaj plaws.
3. Core Application Advantages ntawmHexagon Socket Bolts
1. Ntau dua Load Capacity thiab Zoo Torsion Resistance
Hexagon socket bolts muaj rau lub zog sib xws -cov kabmob nto. Piv nrog cov slotted thiab cross recessed screws nrog tsuas yog ob lub zog- bearing nto, lawv muaj ntau yam kev nyuab siab tis thiab ntau dua torsion kuj. Lawv tiv thaiv cov xov slipping thiab lub taub hau chipping thaum lub sij hawm zawm thiab tuaj yeem tiv taus cov khoom sib dhos ntau dua, ua rau lawv haum rau siab - lub zog fastening scenarios.
2. Countersunk Installation rau du thiab zoo nto
Hexagon socket bolts txhawb countersunk mounting, tso cai rau tag nrho cov ntsia liaj qhov rooj taub hau yuav tsum tau tag nrho embedded nyob rau hauv lub workpiece tsis muaj protrusions. Qhov no ua kom lub ntsej muag du thiab tiaj tus, txhim kho cov tsos zoo, thiab zam cov khoom sib tsoo thiab kev cuam tshuam los ntawm cov ntsia hlau taub hau.
3. Dav Adaptability thiab yooj yim installation & tu
Piv nrog rau sab nraudhexagon bolts, hexagon socket bolts yog hloov tau rau qhov chaw ua hauj lwm tshwj xeeb xws li nqaim, recessed thiab kaw txoj hauj lwm. Lawv tso cai rau kev sib dhos yooj yim, commissioning thiab tom qab kev saib xyuas, thiab muaj feem xyuam rau feem ntau cov cuab yeej siv tshuab, pwm thiab cov cuab yeej cuab tam.
4. Anti-Disassembly Structure nrog kev nyab xeeb dua
Hexagon socket bolts xav tau cov cuab yeej tshwj xeeb hexagonal rau kev teeb tsa thiab tshem tawm thiab tsis tuaj yeem disassembled los ntawm cov wrenches lossis cov ntsia hlau. Qhov no muaj txiaj ntsig zoo tiv thaiv kev tsis sib haum xeeb los ntawm cov neeg tsis yog- cov neeg ua haujlwm tshaj lij, muab kev ruaj ntseg tiv thaiv - tub sab nyiag thiab tiv thaiv - kev ua haujlwm disassembly, thiab txhim kho kev ruaj ntseg thiab kev nyab xeeb ntawm cov cuab yeej siv tshuab.
