HOLO-KROME 09009 براغي كتف 8مم × 20مم | رأس أسطواني | محرك سداسي | فولاذ سبائكي مؤكسد حراري أسود (25/عبوة)

I needed some precise pivot points for a small mechanical assembly, and the hex socket drive made installation straightforward. These shoulder screws fit tightly and the black oxide finish hasn't shown any wear after a few weeks of use.

The ground shoulder on these screws is so precise they slide right into my fixture bearings with zero wobble, making assembly a breeze. A perfect choice for any mechanical build needing a reliable pivot point.

The precision-ground shoulder is exactly what I needed for a pivot joint on a jig I'm building—it's dead on spec and slides through the bearing like butter. Pack of 25 is solid value for the quality.
