ASTM A194

Iyo ASTM A194 yakatarwa inovhara kabhoni, alloy uye simbi isina simbi nzungu dzakagadzirirwa kushandiswa mukudzvinyirira kwakanyanya uye / kana kwepamusoro-tembiricha sevhisi. Kunze kwekunge zvatsanangurwa neimwe nzira, iyo American National Standard Heavy Hex Series (ANSI B 18.2.2) ichashandiswa. Nuts anosvika uye anosanganisira 1 inch saizi yezita ichave UNC Series Kirasi 2B inokodzera. Nzungu dzinopfuura 1 inch saizi yezita ichave iri UNC Series Kirasi 2B yakwana kana 8 UN Series Kirasi 2B yakwana. Simba repamusoro ASTM A194 giredhi 2H nzungu dzakajairika pamusika uye dzinowanzo tsiviwa neASTM A563 giredhi DH nzungu nekuda kwekuwanikwa kushoma kweDH nzungu mune mamwe madhayamita uye kupera.
