براغي ذات رأس أسطواني M5-0.8 X 6mm | محرك سداسي | ملولبة بالكامل | فولاذ سبائكي فئة 12.9 أكسيد أسود حراري (900 / عبوة)

I've been going through a lot of M5 hardware for jig builds lately, and these black oxide socket heads grip my hex keys perfectly without any stripping. The whole pack of 900 came well-organized and the 12.9 grade alloy steel feels noticeably tougher than standard stainless.

These little M5 screws are a perfect fit for my jig fixtures—the black oxide finish looks clean and professional on the tooling. I ordered the 900-pack and every single one has clean threads and a snug hex socket drive.

I needed a batch of small fasteners for a jig I'm building, and these 12.9 grade cap screws fit perfectly into the precision assembly without any wobble. The black oxide coating looks clean and should resist light shop moisture.
