WebbOn a screw micrometer, for 0.5 mm it equals 5 + 0.5 = 5.5 mm. Where 1 strip represents 0.5 mm. But this only applies after passing 5 strips or lines above. When you have crossed the 5 line limit and start to enter the 6th strip, the reading method is different again. The total distance can be read as (5 + 6) x 0.5 mm = 5.5 mm. WebbThe nominal diameter, ball circle diameter, and root diameter are used in calculating the application characteristics and in sizing the screw. Pitch. Pitch is the axial distance between two adjacent threads. Lead. Lead is the linear distance along the axis of the screw that is covered by one complete rotation (3600) of the screw.
