براغي مقبس نقطة كوب 1/2-20 × 5/8 بوصة | فولاذ سبائكي مطلي بالزنك (100/عبوة)

The cup point tip grabbed perfectly on my worn mounting bracket, and the zinc plating seems like it will hold up well against corrosion. I used these for a jig fixture rebuild, and the hex socket drive let me get them snug in a cramped corner without stripping.

The hex socket drive made tightening these set screws a breeze in a tight spot on my milling fixture. The cup point really bites into the shaft without damaging it. Zinc plating looks clean and should hold up fine in my shop.

I needed some high-torque fasteners for a tight spot on a machine, and these set screws with a hex socket drive let me get the perfect bite without rounding. The zinc plating on the alloy steel is clean and consistent across all 100 pieces.
