براغي ضبط رأس مقبس نقطة كوب مخددة 1/2-13 × 7/16" | سبائك فولاذية (100 / عبوة)

The hex drive fits my Allen wrench perfectly without stripping, and the knurled cup point grips securely on my shaft. They came in a nice sturdy 100-pack that will last me through multiple projects.

I needed set screws that wouldn’t slip under high torque in a tight spot, and the hex socket drive on these delivers perfectly. The knurled cup point held the shaft steady during installation, which was a pleasant surprise. Alloy steel feels solid and should last.

The hex socket drive made seating these in a cramped gearbox a breeze, that’s for sure. The knurled cup point bit into the shaft cleanly without any slipping, and the alloy steel feels solid enough to handle serious torque. Just what I needed for a hundred pack.
