براغي ذات رأس أسطواني M12-1.75 × 45 مم | محرك سداسي داخلي | خيط كامل | فئة 8.8 سبائك فولاذية مؤكسدة باللون الأسود الحراري (100 / عبوة)

The black oxide finish looks properly done—no patchy spots or uneven coloring, and the threads are clean all the way down. These 45mm lengths are perfect for my jig builds where I need a full bite without excess sticking out.

The hex socket drive seated perfectly on my Allen key with zero wobble, and the threads ran smooth through my jig plate right out of the bag. For the price per piece on this Class 8.8 alloy steel, I've got no complaints—these will hold up fine in my shop fixtures.

The black oxide finish is holding up well on my lathe’s tool holders, and the hex socket drive makes tightening easy even in tight spots.
