Goliath UNC Intermediate Machine Nut HSS Tap

• 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.
• The 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.
