Socket Head Cap Screw Black Steel 1-8 * 7-1/2" Grade 8 [Cup Point] [Allen Drive] length_5 Alloy steel screws are mildlyWith 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 screws have a thread of 1 8 and a length of 7 1 2. Black oxide steel screws are mildly corrosion resistant in dry environments. Coarse threads are the industry standard: choose these screws if you dont know the pitch or threads per inch. Screws that meet ASTM A574, ASTM A574M, and ISO 898 1 comply with
