Socket Head Cap Screw Black Oxyde Alloy Steel 1/2-13 * 10" Grade 8 [Cup Point] [Allen Drive] Quantity:UnityWith a tensile strength of170, 000psi, these alloy steel screws are stronger than Grade 8 steelscrews. Length is measured from under the head. Black oxide steel screws are mildly corrosion resistant in dry environments. Coarse threads are the industrystandard: choose these screws if you dont know the pitch or threads per inch. Screws that meet ASTMA574, ASTMA574M, and ISO898 1comply with specifications and testing requirements for materialquality.
