Length is measured from under the head. The screw has a length of 5 1 2 and a thread of 1 3 8 12. Alloy steel screws are mildly corrosion resistant in dry environments. Fine and extra fine threads are closely spaced to prevent loosening from vibration: the finer the thread, the better the resistance. They are not compatible with coarse threads.
