Features: Metric Coarse; Angle 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 this general purpose tap is designed for use in medium tensile materials and is for hand or general machine use. ; Specifications:Diameter16 mmPitch2 mmLeadingBottomingOverall Length102 mmTapping Drill14.25 mm
