UNF | Unified National Fine Chrome Alloy Taps

About these taps:
  • Crafted from durable chrome alloy, these taps are designed for cutting and chasing Unified National Fine (UNF) threads, a standard thread form introduced in 1948 to unify thread specifications across the USA, Canada, and the UK.
  • Ideal for cleaning existing threads or creating new female threads in non-ferrous metals and plastics, these taps offer versatility for a wide range of applications.
  • Available in three lead types—Taper, Intermediate, and Bottoming—to suit different stages of the threading process:
    • Taper taps feature a lead of eight threads, making them perfect as starting taps in challenging or high-precision holes.
    • Intermediate taps have a lead of four threads and are commonly used for general-purpose threading, cutting true threads to pre-drilled pilot holes.
    • Bottoming taps possess a lead of two threads, ensuring minimal thread run-out when tapping to the bottom of blind holes, typically used after taper or intermediate taps.
  • The UNF thread profile matches that of metric threads and adheres to the JIS B0206 standard, characterized by its major diameter and threads per inch (TPI).
  • Fine threads in this series provide greater tensile stress area compared to coarse threads of the same size, enhancing resistance to stripping, especially under high load conditions or limited engagement lengths.
  • Chrome alloy taps are suitable for general threading tasks but are not recommended for precision, safety-critical, or high-tolerance threads.

These taps come in a variety of sizes and pitches, ensuring compatibility with a broad spectrum of threading requirements. Each tap is crafted to deliver reliable performance in thread cutting and chasing, making them essential tools for machinists and engineers working with UNF threads.
