How to select the correct OSG tap for UNF threads?

To select the correct OSG tap, match the thread size (e.g., 5/8"-18 UNF) and class fit (e.g., H3 for 2B/3B). Consider material type and coating: TiN suits harder materials. For hand tapping, a plug chamfer and 4-flute design provide balanced cutting and chip evacuation.
