Coarse threads are the industry standard; choose these screws if you donÂ’t know the pitch or threads per inch. Fine threads are closely spaced to prevent loosening from vibration. They are not compatible with coarse threads.
Screws that meet ISO 21269 and ISO 4762 (formerly DIN 912) comply with specifications for dimensional standards.
