براغي ضبط بنقطة كأس مخددة #10-32 × 5/8 بوصة | فولاذ سبائكي مطلي بالزنك (250 / عبوة)

I had to swap out some stripped set screws on a machine vise, and these knurled cup points grabbed the shaft way better than the old smooth ones did. The hex socket drive gave me solid torque even in a tight spot behind the jaw, and the zinc finish hasn't shown any rust after a week of cutting fluid

The knurled cup point grips really tight against the shaft, and the zinc coating looks clean. Had to tighten a stubborn pulley on a mower deck, and these set screws held without stripping.

The hex socket drive fit my hex key perfectly, making it easy to tighten these in a tight spot despite the small size. The zinc plating gave them a clean, consistent finish right out of the package.
