براغي رأس كبس H20-2.5 × 110mm من HOLO-KROME 76528 | محرك سداسي | فولاذ سبائكي مع أسود حراري (10 / عبوة)

The hex socket drive fits my torque wrench perfectly, and the black oxide finish gives them a nice, consistent look across all ten screws. They threaded smoothly into my jig without any binding.

I swapped out some generic bolts on my milling machine fixtures for these, and the black oxide finish is holding up much better against cutting oil residue than the plain steel ones did. The hex socket drive made installation a breeze with my Allen wrench.

These are holding up great in my jig setup—the 110mm length gives plenty of grip, and the thermal black oxide finish has a nice, even look that resists rust. The socket drive seated cleanly without any stripping, which is exactly what I needed for repeated adjustments.
