براغي رأس مقبس M16-2 × 60 مم | محرك سداسي | ملولبة بالكامل | فولاذ سبائكي فئة 12.9 أسود حراري (50 / عبوة)

I needed to replace some worn fasteners on a jig I use daily, and these M16-2 screws threaded in smoothly without any binding. The 60mm length was spot-on for my assembly, and the hex socket drive made tightening a breeze with my Allen key.

The hex socket drive seated perfectly on my wrench, no wobble at all, and the black oxide finish looks evenly applied across all fifty pieces. I’ve used a few of these for a jig build and the 12.9 grade feels seriously stout for the torque I put on them.

These threads cut clean and the black oxide finish is uniform across all 50 pieces, which I appreciate for jig work. The hex socket drive seated perfectly with my Allen key, no wobble or stripped edges.
