-Daidaito da kuskuren ƙira na famfo kanta.
Misali: sarrafa zaren 6H, a cikin sarrafa ƙarfe, na iya zaɓar madaidaicin famfo na 6H;A cikin tsarin simintin simintin launin toka, saboda tsakiyar diamita na famfo yana da sauri, fadada ramin dunƙule yana da ƙananan, don haka ya dace don zaɓar madaidaicin famfo na 6HX, rayuwa zata fi kyau.
-Girman siffar famfo na waje
1. A halin yanzu, mafi yawan amfani da su sune DIN, ANSI, ISO, JIS, da dai sauransu.
2.bisa ga abokin ciniki ta daban-daban aiki bukatun ko data kasance yanayi don zaɓar dace tsawon, gefen tsawon Kuma rike square size;
3. Tsangwama yayin aiki;
Matsa zaɓin abubuwa na asali guda shida:
1, nau'in zaren sarrafawa, metric, Burtaniya, Amurka, da sauransu;
2. Nau'in rami na kasa na zaren, ta rami ko makaho;
3, sarrafa workpiece abu da taurin;
4, da workpiece cikakken thread zurfin da kasa rami zurfin;
5, workpiece thread daidaici;
6, bayyanar ma'aunin famfo (buƙatun na musamman suna buƙatar alama).
