براغي ذات رأس مقبس M1.6-0.35 × 6 مم | محرك سداسي | ملولبة بالكامل | فولاذ سبائكي فئة 12.9 أسود حراري (600 / عبوة)

The black oxide finish looks even better in person, and these 12.9 alloy screws have held up perfectly in my precision fixture after weeks of use. The 6mm length is spot on for what I needed, and the hex socket drive makes them easy to torque without stripping.

Was a bit skeptical about how strong such tiny screws could be, but the Class 12.9 alloy steel feels incredibly rigid when tightening into a jig fixture. The black oxide coating also gives them a nice uniform look without any glare.

For the tiny screws I needed for a precision jig, the hex socket drive made installation much easier than fumbling with a tiny Phillips head. The black oxide finish looks nice and the 600-count pack will last me a long time.
