HOLO-KROME 69378 M5-0.8 × 25mm براغي رأس كب | محرك سداسي منخفض الرأس | فولاذ سبائكي مؤكسد أسود حراري (100/عبوة)

The black oxide finish on these screws gives them a sleek, professional look that matches my machine builds perfectly. They’re consistently clean and drive smoothly into the threads without any binding. Definitely a solid value for the quantity you get.

These M5 screws threaded perfectly into existing tapped holes on my jig fixture, and the low head profile is a real space-saver in tight spots. The black oxide coating seems durable and hasn't chipped during assembly. Really solid hardware for the price.

I’ve been using these M5 low head screws for a jig build, and the thermal black oxide finish feels tougher than standard coatings. The hex socket drive engaged cleanly without any stripping, even when torquing into alloy steel.
