HOLO-KROME 09003 6mm X 16mm براغي كتف بمقبس | رأس مقبس | محرك مقبس | سبائك فولاذية بأكسيد حراري أسود (25 / عبوة)

The precision ground shoulder is dead-on consistent across all 25 pieces, which made setting up as an axle for my roller assembly a breeze. Threads engage smoothly and the black oxide finish looks sharp. Exactly what I needed.

These fit perfectly into my custom jig’s pivot points, and the black oxide finish won’t rust in my damp garage. The hex socket made installation quick with a standard Allen key, and all 25 pieces were packed securely.

I needed a precise bearing surface for a small pivot assembly, and these screws delivered—the ground shoulder is noticeably smoother than standard bolts. The hex socket drive also made installation much easier in a tight spot. Very pleased with the quality.
