براغي مقبس كوب مخدد 5/16-24 X 3/4" | فولاذ سبائكي مطلي بالزنك (100 / عبوة)

The knurled cup point bites into the shaft far better than I expected, and the zinc plating looks clean without any flaking. Used a dozen of these on a fixture build today, and every one seated true with just a few turns of my hex wrench.

The knurled cup point really digs in and holds tight, which was perfect for locking down a sprocket on my project. These screws are solid and the zinc plating looks clean. Exactly what I needed for a secure fit in a tight spot.

Installed these to secure a pulley hub on a custom build, and the hex socket drive let me really torque them down in a tight spot. The knurling on the cup point held firm without marring the shaft surface. Solid little fasteners for precision locking.
