براغي رأس أسطواني M2.5-0.45 × 8 مم | رأس مسطح مع محرك سداسي | ملولبة بالكامل | فولاذ سبائكي فئة 10.9 مع أكسيد أسود حراري (900 / عبوة)

Perfectly uniform threads across the full 8mm length, and the hex socket drive grips cleanly without any stripping on the first few installs. I've used maybe 300 of these in my jigs so far and not a single dud. Exactly what I needed for precision assemblies at this price.

The black oxide finish on these M2.5 screws looks professional and resists scratching during assembly, which is perfect for my small jig project. For the price, getting a full 900-pack of Class 10.9 alloy steel hardware is a steal, and every screw I've used so far threads smoothly.

These screws threaded perfectly into my precision fixture without any galling, and the black oxide finish looks clean and durable. The hex socket drive engaged nicely with my driver, so I didn't strip a single one during assembly. A solid, reliable choice for holding small tooling components togethe
