In ISO metric threading standards, there are coarse, fine (like UNC and UNF for imperial) and even extra-fine. Most of the smaller-diameter threads used on a bike are coarse. A fine 5mm thread has pitch 0.5 mm. Axle threading used on a bike (9 and 10 x 1 or 0.75) is considered fine thread. 35 x 1 mm threading is no doubt extra-extra-fine!
