UNIFIED NATIONAL FINE TAP SETS | UNF BORDO

UNF | UNIFIED NATIONAL FINE TAP SET

About this item:

• Chrome Alloy UNF Hand Tap Sets designed for creating and restoring female threads in non-ferrous metals and plastics.
• Ideal for use as thread chasers to clean existing threads or to form new threads where precision, safety, or critical threads are not required.
• Manufactured with Chrome Alloy, these taps offer durability and reliable performance for general-purpose threading tasks.
• The Unified National Fine (UNF) thread form, introduced in 1948, standardizes thread profiles across the USA, Canada, and the UK, aligning with the JIS B0206 metric thread standard.
• Threads are specified by their major diameter and threads per inch (TPI), with fine threads offering greater tensile stress area and superior resistance to stripping compared to coarse threads of the same size.
• Fine threads are particularly advantageous where engagement length is limited or where wall thickness requires a finer pitch.
• Each tap set includes Bottoming, Taper, and Intermediate taps:
  • Bottoming Taps: Lead of two threads, used to minimize thread run-out in blind holes.
  • Taper Taps: Lead of eight threads, ideal as starting taps in challenging or high-precision holes.
  • Intermediate Taps: Lead of four threads, suited for most general applications to cut true threads in pre-drilled pilot holes.
• Bottoming taps are typically used following Taper or Intermediate taps to complete threading.

These Chrome Alloy Unified National Fine Tap Sets provide a comprehensive solution for threading needs across a wide range of diameters

and thread pitches, ensuring compatibility with standard UNF specifications and delivering dependable results in various workshop and repair scenarios.
