براغي رأس سداسية مجوفة بنقطة كوب M5 × 30 مم | فولاذ مقاوم للصدأ 18/8 (250 / عبوة)

The hex socket drive really shines when you're torquing them into a tight spot—my Allen key grabbed perfectly every time. The 30mm length was spot-on for my application, and the 18/8 stainless feels solid enough to last.

Used them to lock down a pulley hub and the cup point really bites into the shaft, no slipping at all. The hex drive makes it easy to torque them in even with my fingers barely fitting in there.

These set screws held fast when I adjusted the alignment on my CNC fixture, and the hex socket drive made torquing them down in a tight spot a breeze. The 18/8 stainless steel feels solid and durable for the price.
