براغي رأس مقبس سداسي M16-2 × 60 مم | محرك مقبس سداسي | ملولبة بالكامل | فئة 8.8 سبائك فولاذية مؤكسدة سوداء حرارياً (25 / عبوة)

The black oxide finish on these M16 screws looks great and seems to hold up well. The hex socket drive seated perfectly with my Allen key, and the fully threaded body made alignment in my jig a breeze.

Installing these on a piece of machinery this week, and the hex socket drive made tightening them in tight spaces much easier than I expected. The black oxide finish seems durable and gives them a clean, professional look.

Put these to use in a jig I was building for a custom CNC part, and the 60mm length was spot-on for the depth I needed. The black oxide coating gives them a nice, consistent finish that resists wear well so far.
