براغي كتف بمقبس HOLO-KROME 08024 5/16" × 1" | رأس مقبس | محرك مقبس | فولاذ سبائكي أكسيد أسود حراري (25/عبوة)

Used these as the pivot for a jig I'm building, and the hex socket drive made installation a breeze with a standard Allen key. The thermal black oxide finish on these seems durable, and they fit perfectly without any wobble.

I needed a precise bearing surface for a small jig I’m building, and the ground shoulder on these is spot-on. They drove in smoothly with a hex key and feel solid.

These shoulder screws have that perfect hex socket I was hoping for to keep my assembly neat, and the black oxide finish handled a quick test against rust just fine. The precision ground shoulder made setting up a consistent axle for my homemade roller cart effortless.
