Hardness Qib Thiab Daim Ntawv Thov Qhov Zoo Ntawm Hexagon Socket Bolts
Jun 16, 2026
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 cov qib zoo tib yam-lub zog thiab cov qib siab 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 muaj 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 saum toj no yog tsim los ntawm nruab nrab-carbon steel lossis low-alloy steel thiab undergo quenching thiab tempering tshav kub kev kho mob los txhim kho txhua yam khoom, uas txhais tau tias muaj zog bolts. Tag nrho lwm yam uas tsis yog-kub-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 High-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 cev quab yuam-cov kabmob. Piv nrog cov slotted thiab cross recessed screws nrog tsuas yog ob lub zog-cov kabmob qhov chaw, lawv muaj ntau yam kev nyuaj siab faib thiab ntau dua torsion kuj. Lawv zoo tiv thaiv 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 tsim nyog rau cov xwm txheej ceev ceev.
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 tu, thiab dav siv 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 ua haujlwm tsis muaj kev tshaj lij, muab kev ruaj ntseg tiv thaiv tub sab nyiag thiab kev tiv thaiv kev sib tsoo, thiab txhim kho kev ruaj ntseg thiab kev nyab xeeb ntawm cov cuab yeej siv tshuab.
