براغي ضبط سداسية بنقطة كوب محززة 7/16-14 × 1 بوصة | سبائك فولاذ (100/عبوة)

These set screws tightened down securely in a tight spot where my standard hex wrench couldn't reach. The alloy steel feels solid, and the knurled cup point really grips the shaft without slipping.

The knurled cup point tip on these screws really digs in and holds firm, even in tight spaces where I can barely fit a wrench. They tightened down smoothly with a hex key and feel solid as steel should. Exactly what I needed for a stubborn machine guard repair.

I needed some high-torque screws for a tight spot on my assembly jig, and these hex socket drives let me crank them down without stripping. The alloy steel seems sturdy enough for repeated adjustments, and the knurled cup point really holds its position once set.
