HOLO-KROME 87078 براغي رأس مقبس M5-0.8 × 40 مم | رأس مسطح بمحرك سداسي | سبيكة فولاذ أكسيد أسود حراري (100 / عبوة)

Needed some longer M5 bolts for a fixture I was building, and these 40mm ones fit perfectly in the tapped holes. The hex socket drive made installation straightforward with a standard Allen key, and the black oxide coating gives them a clean, professional look.

The black oxide finish on these screws made them slide into the tight holes on my precision assembly without binding. They’re a perfect fit for M5 hardware and the 40mm length was exactly what I needed.

These black oxide screws fit perfectly into my jig setup and the hex drive made installation a breeze. The 40mm length was exactly what I needed for this project.
