Wheel bearing won't have any threads. If your talking about the post they mount on, then you can use a pitch gage to get the number of threads per inch and then compare that to a thread chart to determine if they are coarse or fine.

All thread pitches are standard inch size thread pitches. I can't be more specific than that since I don't know exactly which bolt you are talking about. An example for you is the starter bolts are a 3/8-16 pitch, which is standard coarse thread. Most body panel bolts are either 5/16-18 or 3/8-16 pitch, once again, standard coarse thread pitches.
general use coarse thread bolt is correct. 1/2 inch bolt. 13 threads per inch.

You cannot use a screw to replace a 16 penny nail, as it will not have near enough shear strength. You can easily see this in action by driving a nail halfway into a board, and likewise sinking a screw halfway down. Now hit them both with a hammer perpendicular to their direction of attachment. However, if your application is not structural you will want a 3.5" screw "coarse thread" or about 8 gauge...(coarse thread will look similar to a sheetrock screw thread)
