براغي ضبط رأس مقبس #3/8-16 × 2-1/4" بنقطة كوب | فولاذ سبائكي (100 / عبوة)

Installed these on a jig that sees constant vibration, and the cup point bites in way better than the flat-tip ones I used before. The hex drive made adjusting them in a cramped corner actually doable.

These set screws are perfect for my machinery jigs; the hex socket drives easily even in tight spots. The alloy steel feels really solid, and the full 100-pack means I won’t run out anytime soon.

The cup point tip grabs the material perfectly without walking, and the hex drive lets me torque them down firmly in cramped spots. These screws hold tight even in heavy-use assemblies I've built.
