براغي ضبط بنقطة كوب مقبس سداسي 1/2-13 × 3-1/2" | فولاذ سبائكي (50/عبوة)

The hex socket drive made seating these deep in a cramped bracket way easier than fumbling with a wrench. All 50 pieces came out of the box with clean threads and sharp cup points, and they've held firm under heavy vibration so far.

These cup point screws torqued down perfectly into the jig fixture I was rebuilding. The hex socket drive made it easy to adjust them in a really awkward spot without stripping.

I needed some heavy-duty set screws for a machine tool rebuild and these 1/2-13 cup points fit perfectly. The cup point tip digs in nicely and the alloy steel feels tough enough for repeated adjustments.
