M2.5-0.45 X 18mm براغي رأس مقبس سداسي | محرك سداسي | ملولب بالكامل | فولاد سبائكي فئة 12.9 مطلي بالزنك (600 / عبوة)

I’ve used a lot of M2.5 hardware for jigs, and these are the first ones where the hex socket actually fits a wrench cleanly every time, no rounding off. The zinc plating looks uniform too, which helps when I’m leaving them in a damp shop. For 600 pieces, I’m set for months.

These little screws are surprisingly sturdy for their size, the zinc plating looks clean and uniform across all 600. I’ve used them in a couple of precision jigs and the hex socket drive takes torque without stripping.

Used a dozen of these to secure a jig on a CNC mill, and the 12.9 grade holds up perfectly under vibration. Thread engagement is crisp, no cross-threading issues so far. Great value for a bulk pack.
