HOLO-KROME 08145 براغي كتف بمقبس 3/4" × 4-3/4" | رأس مقبس | قيادة مقبس | فولاذ سبائكي أسود حراري (10 / عبوة)

The precision ground shoulder on these screws is incredibly smooth, making them perfect for a bearing surface in my jig. They threaded in cleanly without any binding, and the thermal black oxide finish looks durable. Exactly what I needed for a heavy-duty pivot point.

The ground shoulder on these screws is dead-on accurate for the replacement axle I needed on an old piece of machinery. They slid into the bore perfectly with zero play, which is exactly what I was hoping for.

Used one as a pivot for a small indexing jig I built, and the hex socket drive made installation dead simple. The black oxide finish also seems tougher than I expected for the price.
