HOLO-KROME 76384 M12-1.75 × 55mm براغي رأس أسطواني | محرك سداسي | فولاد سبائكي مؤكسد حراري أسود (50 / عبوة)

The black oxide coating on these screws gave them a nice, uniform finish that matched perfectly with my machine's aesthetic. They seated smoothly into the threaded holes without any binding, and the hex drive held up well to torque. I’ve ordered a second pack for future projects.

I needed some sturdy fasteners for a jig I was building, and these M12-1.75 x 55mm screws fit perfectly. The hex socket drive made installation much easier than using a hex key on regular bolts.

The thermal black oxide finish on these screws looks great and seems to resist wear better than the plain zinc ones I've used before. I used them to secure a fixture on my mill table, and the hex socket drive made installation in tight spaces much easier.
