HOLO-KROME 64058 5/16-18 X 3/4" براغي ذات رأس أسطواني | محرك سداسي سوكيت | سبيكة فولاذية مؤكسدة حرارياً سوداء (100 / عبوة)

The black oxide finish on these cap screws looks sharp and held up fine during my bench assembly work. Drive engagement is clean with a hex key, no stripping or wobble, and the 100-count box should last me a while.

I was replacing some worn-out fasteners on my jig, and these button heads seated flush with no stripping. The black oxide finish looks clean and should resist rust better than the plain steel ones I used before.

Finally found button head screws that actually hold torque without stripping. The black oxide coating on these 5/16-18 x 3/4" pieces is uniform and looks great on my jig setup. Perfect for precision assemblies where I need a clean, flush finish.
