Low Head Socket Head Cap Screw Fine & Full Thread Black Steel 10-32 * 5/8" 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. Fine threads are closely spaced to prevent loosening from vibration. They are not compatible with coarse threads.

Screws that meet ASTM A574 comply with specifications and testing requirements for material quality.
