Peb ib nrab - xov hex bolts qib 8.8 engineered rau lub load-cov kabmob pob qij txha uas ua kom cov hlau ncej, tshuab thiab cov cuab yeej hnyav. Txhua DIN931 ntsia liaj qhov rooj sib xyaw ua ke qhov tseeb unthreaded shank uas zaum kom raug nyob rau hauv mounting qhov nrog siab -strength threaded kawg, xa cov kev sib raug zoo, superior shear muaj peev xwm thiab kev cia siab rau preload. Lawv yog cov mus-raug xaiv rau steel qauv splicing, thav duab thav duab, machinery bases thiab choj - tseem ceeb kev sib txuas uas qhov chaw thiab shear kev ua tau zoo tsis tuaj yeem cuam tshuam.
Vim li cas thiaj xaiv ib nrab - Xov Hex Bolt (Qib 8.8)
Precise Positioning: lub shank du fits mounting qhov nrog raug kho kom raug, tiv thaiv threads thiab ceev kom tuab - phaj splicing.
Siab Shear Resistance:Qib 8.8 (800 MPa tensile) ntxiv rau tag nrho -section shank yam tsis muaj xov kev ntxhov siab- kev sib zog ua kom muaj kev ntseeg tau ntawm kev sib tsoo- cov pob qij txha tseem ceeb.
Lub neej qaug zog zoo dua: tshem tawm xov cov hauv paus hniav nyob rau hauv lub loaded cheeb tsam txo cov tawg pib nyob rau hauv cyclic thiab dynamic loads nyob rau hauv cov qauv thiab cov cav tov.
Clear Load Path: thaum lub fastener tsuas yog xav tau kawg threading rau cov txiv ntseej kev koom tes, lub shank nqa lub load yam tsis muaj nkim khoom.
Ib nrab vs Full Xov: full- xov txuas tag nrho ntev rau nyias- phaj tuav; ib nrab- xov yog xaiv qhov chaw muaj zog thiab siab shear-load yog qhov tseem ceeb.

FAQ:
Qhov txawv ntawm ib nrab - xov thiab tag nrho - xov hex bolt yog dab tsi?
Ib nrab - xov bolt muaj ib tug du unthreaded shank hauv qab lub taub hau. Lub shank muab qhov sib npaug ntawm qhov sib npaug thiab siab dua shear load peev xwm, thaum threaded kawg koom nrog cov txiv ntoo. Tag nrho- xov bolts koom nrog xov raws tag nrho cov ncej, zoo dua rau nyias - phaj tuav.
Vim li cas Qib 8.8 siv rau cov qauv bolts?
Qib 8.8 muaj 800 MPa nominal tensile lub zog nrog zoo toughness tom qab quench-thiab- temper, ntsuas lub zog, qaug zog thiab nqi rau steel qauv thiab machinery.
Ntev npaum li cas / xov ntev koj tuaj yeem ua tau?
Tag nrho ntev, shank ntev thiab xov ntev yog customizable rau ib daim duab. Cov xov xov feem ntau yog hais txog 2x txoj kab uas hla rau ib nrab - xov bolts
.
Koj puas muab cov ntawv xeem?
Yog lawm, MTC / cov ntaub ntawv pov thawj, tensile, hardness thiab ntsev -cov ntaub ntawv tshuaj ntsuam muaj nyob nrog txhua pawg.
Kuv puas tuaj yeem tau txais cov qauv dawb ua ntej?
Yog, cov qauv muaj; tsocai hauv 1 teev thiab tshwj xeeb muaj feem ntau hauv 24 teev.
