ASTM A194
Ko te taaputanga ASTM A194 e hipoki ana i te waro, te koranu me nga nati kowiri tira e tika ana mo te whakamahi i roto i nga ratonga pehanga-nui me te / ranei. Ki te kore e tohua, ka whakamahia te American National Standard Heavy Hex Series (ANSI B 18.2.2). Ko nga nati tae atu ki te 1 inihi te rahi o te ingoa ko te UNC Series Class 2B kia pai. Ko nga nati neke atu i te 1 inihi te rahi o te ingoa ka uru ki te UNC Series Class 2B pai, 8 UN Series Class 2B pai ranei. He nui noa nga nati ASTM A194 karaehe 2H kaha i te kainga hokohoko, ka whakakapihia ki nga nati DH karaehe ASTM A563 na te iti o te waatea o nga nati DH i roto i etahi waahanga me te whakaoti.

| FAKATOKANGA: 1. Ko nga tohu e whakaatuhia ana mo nga reanga katoa o nga nati A194 mo nga nati hanga makariri me te wera wera. Ina mahia nga nati mai i te rakau, me tohu ano te nati ki te reta 'B'. Ko nga reta H me M e tohu ana i nga nati kua werahia. 2. Ko nga ahuatanga e whakaatuhia ana ko nga nati hex taumaha me te miro 8-pitch. 3. Ko nga nama pakeke ko Brinell Hardness. 4. Ko nga nati e rongoa ana i te warowaiha me etahi atu reta A – 8A, 8MA ranei. 5. Me mau nati katoa te tohu tohu a te kaihanga. Ko nga nati me tino tohu ki tetahi mata hei tohu i te karaehe me te mahi a te kaihanga. Kaore e whakaaetia te tohu i nga papa wiriwiri, i nga papa mauri ranei mena kaore i whakaaehia i waenga i te kaihanga me te kaihoko. Ko nga nati kua pania ki te zinc he whetūriki (*) kua tohua i muri i te tohu tohu. Ko nga nati kua pania ki te cadmium me whai tohu taapiri (+) i muri i te tohu tohu. 6. Kei te noho tonu etahi atu tohu, engari kaore i te raarangi ki konei. Paerewa Whakamau Inihi. 7th ed. Cleveland: Industrial Fasteners Institute, 2003. N-80 - N-81. | ||||||||
