Features:

• METRIC - Coarse & Fine
• Angle of thread is 60°
• 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).
• TAPER TAPS have a lead of eight threads and are used as a starting tap in difficult or high precision holes.
