براغي تثبيت بمقبس سداسي برأس كوب 5/16-24 × 1/4 بوصة | فولاذ سبائكي مطلي بالزنك (500 / عبوة)

For a 500-pack at this price, the hex socket drive makes tightening them in tight spots a breeze. Zinc plating looks uniform across all of them, and I haven't had one strip out yet.

These set screws are a perfect fit for a jig I'm building, and the cup point really bites into the shaft without marring it. The zinc plating looks clean and consistent across all 500 pieces.

I needed a high-torque adjustment in a cramped spot, and these hex socket cup points fit perfectly with no stripping. The zinc plating feels solid, and the whole pack of 500 came neatly organized. Exactly what I needed for locking collars and jig fixtures.
