براغي رأس كبس M8-1.25 × 30 مم | محرك سداسي رأس زر | ملولبة بالكامل | فولاذ سبيكة فئة 12.9 أكسيد أسود حراري (200 / عبوة)

The black oxide finish handled a greasy shop environment without a speck of rust, and the hex socket drive grabbed cleanly every time. I used a full row of these on a steel fixture jig and every one seated flush without stripping.

These M8 button heads fit perfectly into my jig fixture, and the hex socket drive made installation a breeze with no stripping. The fully threaded shank gives me a solid 30mm of grip, which is exactly what tight assemblies require.

The black oxide finish on these is flawless and uniform across all 200 pieces, so they look great even on exposed surfaces. I've torqued several to spec on a fixture and the hex drive hasn't stripped once. These are my new go-to for precision assemblies.
