Bordo 5 x 0.8mm Left Hand Metric Coarse Hand and Machine Tap

• HSS Metric Coarse LEFT HAND Hand and Machine Tap Set

• 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).
