DIN931 Nusu Thread Hex kichwa Bolt chuma cha pua3

Kamba kamili ya bolt inamaanisha kuwa bolt na fimbo iliyotiwa nyuzi zote zimefungwa. Screw ya nusu ya nyuzi ni nusu ya nyuzi na nusu ni fimbo ya poli.

Bolts imegawanywa katika aina mbili: meno coarse na laini kulingana na sura ya nyuzi. Sura ya jino coarse haionyeshwa kwenye nembo ya bolt. Vipu vya kawaida vinaweza kugawanywa katika darasa tatu: A, B, na C kulingana na usahihi wa uzalishaji. Daraja A na B ni bolts zilizosafishwa, na daraja C ni bolts mbaya. Kwa kuunganisha bolts kwa miundo ya chuma, isipokuwa kama ilivyoainishwa vingine, kwa ujumla ni bolts za kawaida za daraja mbaya.

Vipu vya chuma visivyo na waya hurejelea bolts zilizotengenezwa kwa chuma cha pua, pamoja na chuma cha pua cha SUS201, chuma cha pua cha Sus304, chuma cha pua cha Sus316, na chuma cha pua cha Sus316L. Daraja la utendaji wa bolts za chuma, studio na programu zimegawanywa katika darasa 10: kutoka 3.6 hadi 12.9. Nambari kabla ya hatua ya decimal inawakilisha 1/100 ya kikomo cha nguvu ya nyenzo, na nambari baada ya hatua ya decimal inawakilisha mara 10 ya kiwango cha kikomo cha mavuno kwa kikomo cha nguvu ya nyenzo.

Ufungashaji

Tunatoa aina ya ufungaji tofauti ili kukidhi mazingira tofauti ya usafirishaji na udhibiti wa gharama. Aina za kawaida za ufungaji ni pakiti za tani, mifuko ya kusuka, masanduku kwa wingi, masanduku kwenye masanduku, pamoja na pallet au kesi za mbao kukidhi mahitaji ya usafirishaji wa bahari au hewa. Chini ni picha za aina tofauti za ufungaji tunazotoa kwa kumbukumbu.
