Bulk orders will be discounted, please contact us.

UN coarse (UNC) taps have fewer threads per inch than UN fine (UNF) taps. Compared to UNF taps, UNC taps perform better in threading applications on brittle materials and are less likely to cross thread. Coarse threads can also withstand more physical abuse than fine threads. The bright finish on these taps provides a smooth, polished surface.
