براغي رأس مقبس M2.5-0.45 × 12 مم | محرك مقبس سداسي | ملولبة بالكامل | فولاذ سبائك كلاس 12.9 مؤكسد أسود حراريًا (600/عبوة)

Just finished a small jig and these 12mm M2.5s seated perfectly every time—the black oxide finish looks clean and the threads are sharp, no binding. Having 600 in one box means I won't run out mid-project, which is exactly what I needed for production runs.

The hex socket drive on these M2.5s grips the hex key perfectly, with no wobble or slop during tightening. I used them in a jig for a precision assembly and the Class 12.9 alloy steel feels rock solid.

These M2.5 screws are perfectly consistent out of the box, and the black oxide finish has held up great while I've been building jigs in the workshop. The 12.9 alloy steel feels solid and the threads cut cleanly every time; six hundred pieces should last me a good while.
