About this item:
- 1/2" x 13 UNC Intermediate Machine Nut HSS Tap - Goliath
- HSS Bright Finish UNC Machine Nut Intermediate Tap.
- Machine Nut Taps are used where a long shank is needed and are available in Taper, Intermediate, and Bottoming leads.
- To ensure easy and precise use the Machine Nut Tap Taper lead has a unique, very long entering chamfer.
- This makes aligning the cutting end with the work piece simple.
- Ideal for tapping nuts, small quantities made from tough steel such as stainless steel as well as mild steels, or for rethreading rusty or worn threads.
- Alternatively, the Intermediate and Bottoming leads are ideally suited to long reach threading applications where the thread needing to be tapped or cleaned is beyond the reach of a standard tap.
- We recommend the Intermediate lead Machine Nut Tap for long reach through-hole applications and the Bottoming lead for long reach blind hole applications.
- Unified National Coarse thread form was introduced in 1948 as an attempt to standardise thread forms in the USA, Canada and the UK.
- The thread profile of UNC 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).
- This thread series is commonly used in the mass production of bolts, screws and nuts.
- It is used for threading into lower tensile strength materials (bronze, brass, aluminium and plastics) to obtain the best resistance to stripping of the internal thread.
- It is also used on quick assembly or disassembly or if corrosion or slight damage is possible.
