Goliath Bottoming Machine Nut HSS Tap

• HSS Bright Finish Metric Coarse Machine Nut Bottoming 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 workpiece 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 Metric Coarse angle of the thread is 60 degrees.
• The crest is flat and the thread has clearance at the root, allowing external and internal threads to engage well.
• A larger root radius and lower thread height enable easy screw thread processing and increase thread screw strength.
• The major diameter of the external thread and pitch is specified by a simple numerical value (most commonly measured in millimetres).
