Tools & Gear Taps & Dies HSS Hand and Machine Taps

HSS Machine Nut Taps 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. METRIC COARSEAngle of thread is 60 degrees. The crest is flat and the thread has clearance at the root allowing external thread and internal thread to engage well. Larger root radius and lower thread height enable easy screw thread processing and increase thread screw strength. The major diameter of external thread and pitch are specified by a simple numerical value (most commonly measured in millimetres). BOTTOMING TAPS have a lead of two threads and are used to ensure minimum thread run-out when tapping to the bottom of a blind hole. Bottoming Taps are typically preceded by the use of a Taper or Intermediate Tap. Manufactured from HSS.
