براغي M3 × 12 مم برأس كوبية نقطة سداسية | فولاذ سبائكي مطلي بالزنك (1000 / عبوة)

The cup point bites into the shaft really well, so I don't worry about these backing out under vibration. The hex socket drive made tightening them in a cramped motor mount a breeze, and the zinc plating looks clean out of the box.

I needed M3x12 set screws for a small jig and the cup point bites nicely into the shaft without stripping. The zinc plating seems decent enough for light industrial use. Only minor gripe is a couple screws had slightly burred threads.

The hex socket drive makes torquing these down in cramped corners actually manageable. Mine arrived uniformly plated with no rust spots, though a few had slightly tight threads out of the bag. Solid value for a thousand pieces.
