Socket Head Cap Screw Fine Thread Black Steel 1-3/8-12 * 5-1/2" Grade 8 [Cup Point] [Allen Drive] tige_filete This hexagonal bolt has aWith a tensile strength of 170,000 psi, these Alloy steel screws are stronger than Grade 8 steel screws. 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.
