Thread Forming Tap #3-56 Cobalt MPN:1400104401

UN fine (UNF) taps have more threads per inch than UN coarse (UNC) taps. Compared to UNC taps, UNF taps perform better in threading applications on thin-walled workpieces and hard materials. Fine threads provide more tensile strength and shear strength than coarse 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.
