براغي رأس كبس مقبس M6-1 × 25 مم | محرك مقبس سداسي | خيط كامل | سبيكة فولاذ فئة 12.9 مطلي بالزنك (300/عبوة)

For my precision assembly jig, the hex socket drive let me apply plenty of torque without cam-out, and the zinc plating gives them a nice, clean look that resists surface rust. The 12.9 grade steel feels noticeably tougher than standard hardware store screws, too.

I needed exactly 25mm length for a jig fixture I was building, and these M6s threaded smoothly into tapped holes without any binding. The zinc plating seems consistent across all 300 pieces, which is nice.

The zinc plating on these screws looks clean and even, and the hex socket drive made installation into my jig a breeze. Really solid feel to them for the price.
