Selecting the right option
UNF sets suit precision and thin-wall applications where fine pitch is required. Check that the set covers your required size range before ordering. UNF and UNC threads are not interchangeable — confirm the thread specification before cutting.

These general purpose taps are ideal for creating new threads in a wide variety of materials.
Goliath HSS taps provide a high hardness to toughness ratio, compressive and tensile strength, good abrasion resistance and resistance to micro-chipping, ensuring a long tool life.
Unified National Fine (UNF) thread form was introduced in 1948 as an attempt to standardise thread forms in the USA, Canada and the UK.
The thread profile of UNF is the same as for metric threads and is described in the JIS B0206 standard.
The thread is described by its major diameter and the number of threads per inch of length (TPI).
When used on external threads this series has greater tensile stress area than coarse threads of the same size.
Fine series threads will resist stripping out better than coarse threads in areas where the external and mating internal threads are subjected to loads equal to or greater than the capacity of the screw or bolt.
Fine threads are also used where the length of engagement is limited 1-1/4 or where wall thickness demands a fine pitch.
Intermediate Taps have a lead of four threads and are used in most general purpose applications to cut a thread true to a pre-drilled pilot hole.
Manufactured from HSS this general purpose tap is designed for use in medium tensile materials and is for hand or general machine use.
