براغي رأس كبسولة M5-0.8 × 25 مم | رأس زر بمحرك سداسي | ملولبة بالكامل | فولاذ سبائك فئة 10.9 مؤكسد أسود حراريًا (600 / عبوة)

Class 10.9 alloy steel means these won't strip under heavy clamping, and the black oxide finish slid right into my fixture without any binding. The hex socket drive seated perfectly with my Allen key, and having 600 in one box means I won't be reordering for a long time.

The black oxide finish on these screws is holding up great in my shop jig setup without any surface rust after several days of use. The hex socket drive makes them much easier to install than standard Phillips head fasteners in tight spots. For the price per unit, this is a solid buy for anyone doin

Finally, a pack of M5 button heads that actually threads smoothly into aluminum without binding—the black oxide finish holds up great on my jig. Exactly what I needed for rebuilding my CNC.
