Low Head Socket Head Cap Screw Full Thread Black Steel 1/2-13 * 2" Grade 8 [Cup Point] [Allen Drive]

Made of alloy steel, these low-profile screws are nearly twice as strong as their stainless steel counterparts. With half the height of a standard socket head, these low-profile screws fit in tight spaces, but are weaker than standard socket heads. Length is measured from under the head.

Black-oxide steel screws are mildly corrosion resistant in dry environments. Coarse threads are the industry standard: choose these screws if you don’t know the pitch or threads per inch. Screws that meet ASTM A574 comply with specifications and testing requirements for material quality.
