براغي تثبيت M24 X 50mm بنقطة كوب | فولاذ سبائكي (25/عبوة)

The cup point really bites into the shaft—I was worried about slippage under heavy torque, but these held firm on a stubborn pulley. The alloy steel feels dense and solid too, definitely not the cheap stuff you sometimes get in a 25-pack.

The hex socket drive made tightening these in a tight spot way easier than fumbling with a wrench. Cup point bites into the shaft firmly and the alloy steel feels solid enough for repeated adjustments, happy with the 25 pack for the price.

I needed a set screw that wouldn't slip under heavy load, and the hex socket drive makes adjusting these in tight spots a breeze. The cup point really digs in and holds fast.
