براغي ذات رأس مقبس M14-2 × 100 مم | محرك مقبس سداسي | خيط جزئي | فولاذ سبائكي فئة 12.9 مطلي بالزنك (25 / عبوة)

The partially threaded shaft on these screws gave me just the right clamping force for my jig assembly, and the zinc plating looks clean and durable. They threaded smoothly into tapped holes without any binding.

The hex socket drive made installation a breeze with my torque wrench, and they’ve held up perfectly under constant pressure in my jig build. The zinc plating looks clean and should resist rust around coolant.

After struggling with cheaper bolts that kept stripping, these are a massive upgrade. The Class 12.9 alloy steel feels incredibly hard, and the hex socket drive makes installing them in tight spots a breeze.
