"Turns" refers to the number of trips the balls make around the screw shaft before being recirculated. The relationship between circuits and turns is influenced by the recirculation method. Ball returns that use the deflector or thread-to-thread (aka cross-over) method recirculate each.
This is expressed in a metric number like 1.25 or .8. This references 1.25 threads per 1 mm of length. This makes determining the pitch more difficult, as an 8mm bolt can be 1.25 or 1, and 10mm can be 1.5, 1.25 or 1, each is a different count. Metric bolts are typically labeled as standard or fine, but not always.
