براغي تثبيت ذات رأس كوبي M3 × 30 مم | فولاذ مقاوم للصدأ 18/8 (250 / عبوة)

I was worried about stripping the hex drive on these tiny screws, but the stainless steel held up perfectly under high torque. The cup point really bites into the shaft, so my adjustments stay put even with vibration.

For the tiny fasteners on my RC racing drone, the hex socket drive lets me torque these down precisely without stripping the head. The cup point tip gives a clean, flush fit against carbon fiber parts.

The 18/8 stainless feels solid and corrosion-resistant, and the cup point tip seated perfectly in the aluminum bracket I was mounting. These are a great upgrade from standard pan heads for a cleaner look.
