DIN 604 Flat Countersunk Square Neck Bolt (Nib Bolt)
DIN 604 Bolt yog dab tsi?
DIN 604 ntsia liaj qhov rooj, tseem hu ua aflat countersunk square neck bolt los yog nib bolt, yog tsim los rau kev siv qhov twg aflush nto thiab tiv thaiv - tig khoob leeg yuav tsum tau.
Tsis zoo li tus qauv hexagon bolts, DIN 604 nta 90℃countersunk taub hau uas zaum zoo kawg nkaus nrog cov khoom nto, tshem tawm cov phom sij. Qhov tseem ceeb, lubsquare nuvnyob ncaj qha rau hauv qab lub taub hau tom rau hauv lub substrate (feem ntau yog ntoo los yog steel phaj) raws li torque yog thov. Qhov kev tsim no tiv thaiv cov ntsia liaj qhov rooj los ntawm kev sib tw, tso cai rau ib leeg - sab sib dhos- qhov zoo tshaj plaws hauv qhov chaw kaw lossis kev tsim ntoo hnyav.
DIN 604 vs. DIN 603: Qhov txawv ntawm kev tsim qauv tseem ceeb
Txawm hais tias feem ntau tsis meej pem, cov qauv no ua haujlwm rau cov khoom siv sib txawv. Xaiv qhov tsis ncaj ncees lawm profile tuaj yeem cuam tshuam cov qauv kev ntseeg siab lossis kev xav zoo nkauj.
| Feature | DIN 604 (Tshooj Countersunk) | DIN 603 (Round Head) |
|---|---|---|
| Lub taub hau Profile | Flat / Flush nrog nto | Dome / Protruding |
| Lub luag haujlwm tseem ceeb | Aerodynamic / Kev nyab xeeb nto; Heavy structural joinery | General ntoo thav duab; Kho kom zoo nkauj tiav |
| Hauv qab | Square Nib (Anti{0}}rotation) | Square Neck (Anti{0}}kev sib hloov) |
| Hom Siv Case | Choj decking, Tshuab thav duab, Hnyav ntoo | Fencing, vaj rooj tog, teeb kev tsim kho |
Engineering Note: Yog tias koj qhov kev tsim tshwj xeeb xav tau qhov chaw du los tiv thaiv snagging lossis txo cov cua tsis kam (xws li, ntawm cov qauv choj), DIN 604 yog qhov yuav tsum tau xaiv
Cov ntawv thov tseem ceeb hauv Kev Lag Luam hnyav & Infrastructure
DIN 604 bolts tsis yog "ntoo screws"; lawv yog cov siab -kev ua tau zoo fasteners siv nyob rau hauv qhov xav tau ib puag ncig.
Heavy Timber Construction (Glulam) Siv rau hauv kev sib txuas laminated veneer lumber (LVL) thiab glulam beams qhov twg lub taub hau protruding yuav cuam tshuam nrog kev xa khoom lossis kev nyab xeeb.
Infrastructure & Choj: Qhov tseem ceeb rau kev ruaj ntseg decking ntawm cov neeg taug kev txuas hniav thiab kev taug kev. Cov dej ntws tawm kom tsis txhob muaj kev phom sij rau kev mus ncig, thaum lub square nib tuav cov kev vibration loads ntau hauv ko taw tsheb.
Agricultural & Earthmoving Machinery: Siv nyob rau hauv kev sib sau ua ke ntawm kev sib sau ua ke thiab tsheb laij teb, tshwj xeeb tshaj yog qhov uas lub taub hau taub hau yuav tsum tsis txhob ntes cov qoob loo lossis cov khib nyiab.
Khoom Specifications & Corrosion Resistance
Xaiv cov qib khoom raug yog qhov tseem ceeb kom ua tau raws li lub zog tensile thiab ib puag ncig ntawm koj qhov project.
Carbon Steel (Qib 4.8 / 8.8) Cov txheej txheem kev lag luam rau kev tsim kho. Qib 8.8 raug pom zoo rau siab - thauj khoom sib txuas uas xav tau lub zog tensile siab.
Stainless hlau (A2-70 / A4-80)
A2 (304) Haum rau qhov chaw sab hauv tsev lossis chaw nyob sab nraum zoov.
A4 (316) Yuav tsum tau ua rau thaj chaw hauv hiav txwv lossis cov qauv raug rau kev ntsev thiab tshuaj lom neeg.
Surface Finishes: For carbon steel applications, Hot Dip Galvanizing (HDG) is strongly recommended over standard zinc plating. HDG provides a coating thickness of >45µm, muab kev tiv thaiv zoo tshaj plaws tiv thaiv xeb hauv cov phiaj xwm sab nraum zoov.

Yog vim li cas Manufacturing Precision Matters
Tsis yog tag nrho DIN 604 bolts yog tsim los rau tib lub siab ntev. Hauv kev siv cov qauv, kev sib txawv me me hauv qhov square nib loj tuaj yeem ua rau "camming out" (slipping) thaum lub sij hawm installation, ua rau lub workpiece puas.
Peb Cov Qauv Tsim Khoom:
Precision Cold forming: Peb siv high-tonnage txias taub hau los xyuas kom meej lub square nib yog zoo kawg nkaus nyob nruab nrab thiab loj me me kom tom zoo yam tsis tau tawg cov ntoo.
Kev kho cua sov tsis tu ncua: Batch- tswj hardening kom ntseeg tau tias Qib 8.8 bolts ua tau raws li qhov yuav tsum tau ua kom tawv tawv (250-320 HV) yam tsis muaj nkig.
Xov Accuracy: 6g kam rau ua chav kawm threads xyuas kom meej cov txiv ntoo sib dhos thiab pom cov khoom xa tawm.

Koj puas muaj cov cai tshwj xeeb rau lub zog tensile lossis txheej thickness?
Peb muab DIN 604 bolts ua raws li EN 15048 thiab ISO cov qauv rau cov phiaj xwm tseem ceeb. Hu rau peb pab pawg engineering hnub no rau daim ntawv pov thawj zeb xeem (MTR) thiab cov nqi sib tw ntawm kev txiav txim ntau.
