UNC, UNF ve UNEF Diş Tablosu

UNC, UNF, UNEF diş dibi üstü, matkap delik çapı ve hatve adım bilgilerini bulabileceğiniz tabloları yazımızda bulabilirsiniz.

UNF ve UNC diş ölçülerinde 60°’lik diş açısı bulunur. Kısaltılmış isimlerinin açılımları ise sırayla “Unified National Fine Thread” ve “Unified National Coarse Thread” dir.

Erkek olan (Dıştan dişli) UNF bağlantı noktalarında dişin kesit eksenleri birbirine paraleldir yani düzdür. Sızdırmazlık için en uygun olanı oringtir. Bu dişlerde bakır pul, teflon bant ve sızdırmazlık sıvıları dişler için uygun değildir ve kullanılmazlar.

UNC – Unified Coarse Thread. The old definition NC – National Coarse is comparable with the metric thread. The new term UNC is comparable with the ISO metric thread. NC and UNC threads are interchangeable, in an similar manner to the metric and the ISO metric thread.
