براغي تثبيت مقعرة الرأس M3 × 5 مم | فولاذ سبائكي (1000 / عبوة)

I was worried about stripping the heads on these tiny M3s, but the alloy steel is plenty tough for the torque I put on them. The cup point bites into the shaft well and holds firm under vibration. A full thousand pack means I'll have spares for years.

The hex drive on these M3 screws bites perfectly, letting me tighten them in a cramped panel without stripping. Cup point seats flush where flat heads would stick out. Exactly the rigid hold I needed for a jig that sees constant adjustment.

Exactly what I needed for a fixture I was assembling—the hex socket drive made seating them in tight spots painless. All 1000 pieces came clean with threads intact, which is more than I can say for some other hardware lots I've bought.
