براغي مقبس نقطة كوب مخددة 7/16-14 × 7/16 بوصة | فولاذ سبائكي (100 / عبوة)

Used a batch on a heavy-duty jig frame where vibration is constant, and these set screws haven't budged in months. That hex socket drive made installation a breeze even in a cramped corner, and the alloy steel feels solid without any flex.

The knurled cup point really digs in and holds tight, which is exactly what I needed for a stubborn alignment job. The hex socket drive made torquing them down in a cramped bracket a breeze.

I needed a set screw that wouldn't slip under vibration, and these knurled cup points dig in exactly as promised. The alloy steel feels solid, no stripping or rounding out even after multiple adjustments.
