براغي رأس أسطواني M3-0.5 X 16mm | رأس مسطح سداسي داخلي | كامل الخيط | ستانلس ستيل 316 (800/عبوة)

Bought a pack for a small robotics project and the fully threaded design made assembly much easier. The 316 stainless steel feels noticeably more corrosion-resistant than the cheaper 304 stuff I’ve used before.

The hex socket drive on these M3 screws makes them much easier to work with in tight spaces compared to standard Phillips heads. They threaded smoothly into aluminum without any galling, and the 316 stainless feels like it’ll hold up well against corrosion.

The flat head sits perfectly flush in my jig plate, and the hex drive makes installation quick without stripping. The 316 stainless is exactly what I needed for a small marine electronics project where corrosion resistance matters.
