براغي رأس كبسولة M14-2 × 50 مم | محرك مقبس سداسي | ملولبة بالكامل | فولاذ سبائكي فئة 12.9 مطلي بالزنك (50 / عبوة)

The hex socket drive makes these screws super easy to tighten down in tight spaces, and the zinc plating gives them a clean, consistent finish. I've already used most of the pack on a new tooling project with zero issues.

I've been using these in my jig builds and the hex socket drive makes installation a breeze with no cam-out issues. The zinc plating seems durable and they hold torque well in tight spaces.

These bolts threaded smoothly into my milling fixture without any binding, and the zinc coating looks uniform across all 50 pieces. For the price, you're getting genuine Class 12.9 strength that holds up perfectly under heavy clamping loads.
