براغي كتف بمقبس HOLO-KROME 08121 5/8" × 4-3/4" | رأس مقبس | محرك مقبس | فولاذ سبائكي بأكسيد حراري أسود (10 / عبوة)

I needed a strong pivot for a jig I was building, and these shoulder screws fit the hole perfectly with no slop. The hex drive seated easily with my Allen wrench, and the black oxide finish looks solid.

The precision ground shoulder on these screws made alignment a breeze when I used them as bearings for a custom jig. They fit snugly into the bore with zero wobble, which is exactly what I needed for smooth rotation.

Installed these as pivot pins on a gate hinge and the precision ground shoulder turned out to be exactly what I needed for smooth rotation. The black oxide finish seems tough enough to resist a few rain splashes, too.
