UNF (Unified National Fine) and UNC (Unified National Coarse) inch hand taps are tools for making threads on workpieces according to the Unified National Thread (UN) thread standard in the United States.
Hand Tap UNF inch (Fine): Used for fine threads with tighter thread spacing, suitable for applications that require strength and precision.
Hand Tap UNC inch (Coarse): Used for coarser threads with wider thread spacing, ideal for fast fitting or fastening.
These two tools help create standard-compliant UNF or UNC threaded threads, important in the US industry and in other countries adopting the inch sizing system.
