Thread Forming Tap #4-40 Cobalt MPN:1400105301

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 black-oxide finish on these taps retains lubricants to improve the taps' wear resistance and chip flow. Black-oxide taps should only be used on ferrous metals.
