HOLO-KROME 76184 براغي رأس أسطوانية M6-1 × 35 مم | محرك سداسي | فولاذ سبائكي مؤكسد أسود حراريًا (100 / عبوة)

I've been using these in a jig fixture for heavy-duty clamping, and the 35mm length gives me just the right thread engagement. The hex socket drive lets me torque them down without stripping, even in tight spots.

The black oxide finish on these screws is really uniform and seems durable. They threaded smoothly into my aluminum jig plate without any binding. Exactly the right length for my setup.

Used a dozen of these to rebuild a jig at work, and the black oxide finish took the torque without any galling. Threads ran smooth all the way into the tapped holes. Will grab another pack for the next project.
