Yes, bolts with fine thread will produce about 10% more clamping force than coarse bolts of the same grade. This is due to the differences in cross-sectional areas. The thread roots of the coarse threaded bolt are deeper than those of the fine threaded bolt. Therefore, the fine thread series has a larger stress area and can support more load.
