Fine threads have more threads per inch so this will give you more gripping area in a smaller length For example a 1 4″ bolt comes in 1 4″ 20 which is coarse thread – and has 20 threads per inch Whereas a 1 4″ 28 finely threaded bolt has 28 threads per inch A finely threaded bolt will allow you more threads on a shorter bolt

Resistance A coarse thread is longer than a corresponding fine thread This means there is more material present between threaded flanks This helps the thread to attain a perfect fit and avoid stripping and cross threading Overall this leads to safe and secure engagement over fine threads Plating Buildup Coarse threads are less affected

It may be the case that an 8mm bolt only comes in those two thread pitches thus the temptation to use the SAE terms quot coarse quot and quot fine quot However that is not always the case with other sizes For example 10mm bolts are commonly available in 1 0 1 25 and 1 5 thread pitches Whereas almost all 10mm bolts used on German made vehicles are of the 1 5 variety on a Japanese
