براغي رأس مقبس M3-0.5 × 18 مم | رأس زر بمحرك سداسي | ملولبة بالكامل | فولاذ مقاوم للصدأ 18/8 (1800 / عبوة)

Used a full pack of these on a custom jig and every single one threaded in smoothly without any binding or galling. The 18/8 stainless finish is clean and uniform, which made assembly look professional.

Finally, a bulk pack of M3 screws that actually have clean threads all the way through. The hex socket drive grips well without stripping, even when tightening into aluminum jigs.

I use these M3 socket cap screws to secure aluminum brackets on my jig builds, and the 18/8 stainless steel resists corrosion exactly as needed. The hex socket drive grips tightly without stripping, even after repeated adjustments. Exactly the reliable hardware my precision assemblies required.
