Taw qhia rau Square Head Bolts?
I. Basic txhais & National Standard Specifications
Square taub hau bolts, abbreviated li square bolts, feature ib square -puab lub taub hau thiab fastened nrog cov txiv ntseej. Muaj ob lub teb chaws Suav tus qauv muaj xws li:
1.GB/T 8-2021 Qib C Square Lub Taub Hau Bolt (General ntxhib tiav hom, feem ntau siv hauv khw)
2. GB / T 35-2013 Qib B Me Me Square Lub Taub Hau Bolt (Precision machined rau precision khoom, me me qhov ntev nrog siab dua qhov tseeb)
German Standards: DIN478 (Square Head Bolt nrog dab tshos), DIN479; American Standard: ASME B18.2.1
II. Ob Lub Ntsiab Cai
1. Standard Square taub hau Bolt (GB / T8)
Nws muaj lub taub hau square tsis muaj lub xub pwg dab tshos. Fastening yog ua tiav los ntawm gripping lub taub hau square nrog ib tug wrench; lub taub hau nyob twj ywm tsis- plam thiab ruaj khov nyob rau hauv siab torque nruj.
2. Square Neck Bolt (Square taub hau nrog dab tshos, GB / T12 Round Head Square Neck, DIN603)
Ib tug square locking caj dab extends hauv qab lub taub hau ntsia liaj qhov rooj. Thaum lub sij hawm installation, lub caj dab xauv rau hauv ib lub square qhov ntawm lub workpiece. Tag nrho cov ntsia liaj qhov rooj yog tsau tiv thaiv kev sib hloov thaum zawm cov txiv ntoo, yog li tsis muaj lub cuab yeej ntxiv los tuav lub taub hau. Nws yog tsim tshwj xeeb rau cov pwm thiab T-slot tooling fixtures.
III. Core Structural Advantages
1.Anti-kev sib hloov & qhov chaw (feem ntau tseem ceeb)
Lub caj dab square kaw rau hauv cov square slots, kho lub ntsia liaj qhov rooj nyob rau hauv qhov chaw thaum lub txiv ntseej zawm, cia ib tug - tes fastening. Ib qho yooj yim hex bolts xav tau ob lub wrenches rau txee- zawm.
2. High wrench compatibility kam rau ua
Plaub qhov chaw sib cuag tiaj tiaj haum qhib- kawg thiab kho tau wrenches yooj yim, tiv thaivplamnyob rau hauv greasy tej yam kev mob, tsis pom kev los yog dig muag los ua ke; hex bolts xav tau qhov tseeb angular alignment.
3. Loj bearing cheeb tsam rau hnyav load kuj
Qhov kev txhawb nqa dav dav ntawm lub taub hau square zam kev ua haujlwm crushing nyob rau hauv siab nruj thiab cuam tshuam cov loads, ua rau nws yog ib qho kev xaiv sab saum toj rau railway thiab hnyav machinery.
4. Superior torque kuj
Uniform kev ntxhov siab faib thoob plaws cov phab ntsa square ua rau Qib8.8thiab10.9siab- lub zog bolts kom tiv taus lub zog nruj heev yam tsis muaj kev sib tw lossis tawg lub taub hau kaum.
IV. Common Materials & Strength Qib
1. Qib 4.8Carbon Steel (Q235, SM50B): Dub oxide, electro-galvanized tiav; siv rau kev txhawb nqa zoo tib yam, guardrails thiab lub teeb - khoom siv.
2. Qib8.8Alloy Steel (45 #, 40Cr): quenched thiab tempered rau HRC 27-32; siv nyob rau hauv kev tsim kho machinery, railways thiab hnyav- load steel qauv.
3. 304 / 316Stainless Hlau: Rau corrosive chemical ib puag ncig thiab cov khoom siv sab nraum zoov, xeb - pov thawj yam tsis muaj electroplating.
Kev kho saum npoo: Dub oxide, electro-galvanizing, kub-dip galvanizing, Dacromet txheej.
V. Main Application Scenarios
1.Tshuab cuab tam T-slots, tooling fixtures,pwmsiab daim hlau (Pib daim ntawv thov ntawm square caj dab bolts)
2.Railway lem, tsheb carriages, hnyav lifting khoom, mining machinery
3. Steel qauv rhiav, kav dej txhawb nqa, ntauwd cranes, loj photovoltaic brackets
4.Cov cuab yeej cuab tam qub txeeg qub teg, retro hlau ua haujlwm, tshuab ua liaj ua teb, cov khoom pov tseg tsheb thauj khoom
5.Cov khoom sib txuas cov ntsiab lus nrog qhov muag tsis pom kev, hnyav roj paug los yog qhov chaw nqaim
VI. Qhov tseem ceeb sib txawv ntawm Hex Head Bolts
1.Kev tiv thaiv - kev sib hloov: Square caj dab bolts tuaj nrog ua - hauv cov qauv xauv; hex bolts tsis muaj qhov chaw ua haujlwm.
2. Kev khiav hauj lwm: Square taub hau tso cai siab - kam rau ua qhov muag tsis pom kev sib dhos; hex bolts xav tau kev sib raug zoo.
3. Txoj hauj lwm: Square bolts xauv rau hauv cov qhov rau qhov chaw ruaj khov; hex bolts tsuas yog ua haujlwm yooj yim fastening.
4. Daim ntawv thov: Hex bolts yog universal standard fasteners; square taub hau bolts yog tsim rau hnyav loads thiab cov cuab yeej positioning tshwj xeeb ua hauj lwm tej yam kev mob.
