براغي ضبط بمقبس نقطة كوب 1/2-13 × 1/4 بوصة | فولاذ سبائكي (250/عبوة)

These screws held perfectly after several adjustments on a jig I was building. The cup point digs in nicely without slipping, and the alloy steel feels much tougher than the stainless ones I’d used before.

I needed a hex socket drive set screw that could handle repeated adjustments without stripping, and these alloy steel ones definitely deliver. The cup point digs in nicely on my machine's shaft collars.

These screws are perfect for my jig fixtures; the hex socket drive lets me really crank them down in tight spots without stripping. I grabbed a 250-pack, and every single one has clean threads and a consistent cup point. Great value for the quantity you get.
