HOLO-KROME 73092 5/16-24 X 2" براغي ذات رأس أسطواني | محرك سداسي | فولاذ سبائكي مؤكسد أسود حراريًا (100/عبوة)

I needed some strong screws for a precision assembly jig, and these 5/16-24 x 2" cap screws fit perfectly with their hex socket drive. The black oxide coating gives them a nice look and seems durable.

I was replacing a worn-out jig on my milling machine and these fit the existing tapped holes perfectly with no wobble. The hex socket drive engaged cleanly every time, even when torquing to spec. A solid buy for anyone needing strong fasteners.

The black oxide finish on these screws looks fantastic and seems like it'll hold up much better than standard zinc plating. I used a dozen to secure some heavy jig hardware, and the hex drive seated perfectly without any stripping. These are exactly what I needed for precision work.
