براغي ذات رأس أسطواني M14-2 × 50 مم | محرك سداسي | كاملة الخيوط | فولاذ سبائكي فئة 8.8 مع أكسيد أسود حراري (50 / عبوة)

The thermal black oxide finish on these screws looks great and seems durable. They fit perfectly in my milling fixture without any wobble, and the hex socket drive made installation effortless.

Finally, some M14s that actually thread smoothly into my jig fixtures without binding. The hex socket drive grips perfectly, and the 50mm length is spot on for clamping thick steel plates.

The black oxide finish on these screws gives them a nice, consistent look and seems to resist surface rust well. They threaded smoothly into my jig fixture without any binding. Perfect for the price, especially for a 50-pack of Class 8.8 hardware.
