Socket Head Cap Screw Black Steel 1-1/8-7 * 8" Grade 8 [Cup Point] [Allen Drive] id_1-1-2 They have a standard shoulderWith 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 1 8 7 and a length of 8. 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
