s: Upamhi mhiri kwemafurati emusoro une hexagonal
k: Kureba kwemusoro une hexagonal
ds: Shank dhayamita
d: Kuwanda kweshinda
L: Kureba
ASTM A325 idanho rekuita rinotsanangura kuumbwa kwemakemikari, mashandiro emuchina, uye dimensional zvinodiwa kune hombe hex musoro zvimiro zvekusimbisa.
MaA325 screws anogaroiswa ane nzungu nemawachi kuti aburitse zvakasimba, zvisingachinjiki zvinosungirira mumajoini akakwirira{1}.
Hunhu hwakakosha hunosanganisira:
High tensile uye shear simba
Kupikisa kuneta kwemaitiro
Consistent mechanic performance pane mabhechi
Kushandiswa kwakachengetedzeka mukutakura mutoro{0}kune maassemblies esimbi
Madiro Enguva
Thread size: 1/2"kusvika 1-1/2" (metric yakaenzana iripo)
Chimiro chemusoro: Heavy hex head (yakakura kupfuura yakajairwa hex misoro yekuwedzera torque)
Thread type: UNC (yakakora) kana 8-shinda yakatevedzana yehukuru Hukuru pane kana kuenzana ne1"
Zvishandiso: Epakati-kabhoni simbi (yakadzima uye yakapfava)
Mechanical properties: Minimum tensile simba re120 ksi (827 MPa) ye 1/2" kusvika 1" saizi; 105 ksi (724 MPa) ye 1-1/8" kusvika 1-1/2" saizi
Giredhi/Kirasi Yakaenzana
ASTM A325 yakaenzana neF1852 (itsva chiyero chetension control bolts) mukuita asi inosiyana munzira yekuisa.
Haisi kuenzaniswa zvakananga nemametric mamakisi, asi simba rayo rinosvika ISO 8.8 uye 10.9 makirasi mune chaiwo maapplication.
Inowanikwa mumhando mbiri:
Type 1: Carbon simbi (yakajairika)
Type 3: Weathering simbi (yekudzivisa ngura mumashandisi ekunze)
Nguva Yekushandisa A325 Screws vs Regular Hex Bolts
ASTM A325 screws inosiyana kubva kune akajairwa hex mabhaudhi munzira nhatu dzakakosha:
1. Mutoro Kukwanisa
A325 fasteners akagadzirirwa kutakura yakakwirira tensile uye shear mitoro.
2. Specification Testing
Imwe neimwe yekusimbisa inosimbiswa inopesana neASTM maitiro ekuita.
3. Maitirwo Ekuvaka
Yakanyanya kutaurwa mune zvimiro zvesimbi dhizaini makodhi uye mainjiniya maratidziro.
Izvi zvinoita kuti A325 screws ifarire kupikuvimbika kwechimiro kwakakosha- kunyanya pakujoinha zvikamu zvesimbi zvakafara, tension yakakosha kubatanidza, kana kudzokororwa kudzokororwa nzvimbo.
Inch & Metric Size Chati - Gwaro reSarudzo
Pazasi pane chati inoshanda inosanganisa humambo uye metric zviyero zvinowanzoshandiswa kune A325 fasteners mumisika yepasi rose:
🔩 Diameter & Thread Pitch
| Imperial Size | Nominal Metric | Thread Pitch (mm) | Typical Application |
|---|---|---|---|
| 1/2" | M12 | 1.75 | Chiedza kusvika pakati nepakati |
| 5/8" | M16 | 2.0 | Pakati pemaitiro |
| 3/4" | M20 | 2.5 | Heavy structure |
| 7/8" | M22 | 2.5 | Extra heavy simbi |
📏 Kureba Kurudziro
| Finish Condition | Kureba kwakafanana (Inch) | Metric Equivalent (mm) | Kushandiswa kwakajairika |
|---|---|---|---|
| Standard Fastening | 2" | 50 | Chikamu chimwechete chinobatana |
| Tension Critical | 3" | 75 | Zvikamu zvedandemutande zvakadzika |
| Heavy Structural | 4"–6" | 100–150 | Magungano-akawanda |
| Custom | 8"–12" | 200–300 | Unique engineered zvinodiwa |
Maitiro ekuisa A325 Screws yeKuita Kwakanakisa
Kuisirwa kwakaringana kunowedzera hupenyu hunoshanda hwekubatanidza kwako:
✔ Matanidza saizi yebhaudhi uye shinda inonamira chaizvo nenzungu uye washer
✔ Shandisa maturusi etorque akaremerwa kudzivirira pasi-kuomesa kana kupfupikisa{1}}kupfuura
✔ Simbisa pekugara kwakakodzera usati wazara mutoro application
✔Shandisa-zvishandiso zvinodzivirira kutenderera uko kunotarisirwa kuzunguzika
Yakakodzera torque kutonga inovimbisa kunyangwe mutoro kugovera uye inovandudza chengetedzo mumagadzirirwo masisitimu.

Mibvunzo Inowanzo bvunzwa
Mubvunzo: A325 screws inogona kushandiswa panzvimbo yemabhaudhi akajairwa here?
A: Chete kana dhizaini inoda ASTM-yakayerwa simba. Kune-makonesheni akakosha, mabhaudhi enguva dzose anogona kukwana.
Mubvunzo: Aya akakodzera kushandiswa kwekunze kwemaitiro?
A: Hongu - kunyanya ine dip inopisa yakanangidzirwa kana kuti mechanic galvanizing.
Q: Ndeupi musiyano uripo pakati peA325 neA490?
A: MaA490 fasteners akasimba uye anowanzo shandiswa munzvimbo dzakakwirira-makonesheni ezvimiro.
Sei Kusarudza Yedu A325 Fasteners
Isu tinoburitsa A325 hex musoro screws ayo ari:
✔ Yakagadzirwa kune ASTM A325 yakatarwa
✔ Yakarurama muhukuru uye shinda mbiri
✔ Inowanikwa neakawanda epamusoro ekudzivirira sarudzo
✔ Inotsigirwa nemhando yekuongorora mishumo
✔ Inotsigirwa zvizere nehuwandu hweprojekiti uye zvinodiwa neOEM
Zvingave zvemabhiriji, nhandare, zvidyarwa zveindasitiri, kana masisitimu ezvimiro, zvisungo zvedu zvakavakwa kuti zviite.
Mhedziso
Iyo ASTM A325 Hex Head Screw ndeyepamusoro-kusimba, inorema-basa rekusungirira rakagadzirirwa kubatanidza simbi. Nezvivakwa zvayo zvakamisikidzwa, mamakisi akasiyana (Type 1 & Type 3), uye akawanda anopedza, inoramba iri imwe yeakavimbika mabhatani ekuvaka uye einjiniya mapurojekiti pasi rese. ASTM A325 Hex Musoro Screws zvinhu zvakakosha muinjiniya yezvimiro, zvinokosheswa nekuda kwesimba ravo repamusoro uye kuvimbika.
