براغي غطاء مقبس M14-2 X 140mm | محرك مقبس سداسي | ملولب جزئيًا | فولاد سبائكي فئة 12.9 مطلي بالزنك (25 / عبوة)

The partially threaded design made aligning these in my milling fixture so much easier than fully threaded bolts. They tighten down smoothly with a hex key and feel incredibly solid for precision work. Very happy with this pack for tooling projects.

I’ve been using these for a jig build and the Class 12.9 strength is holding up way better than the standard 8.8 bolts I used before. The hex socket drive lets me get them snug without stripping the head.

The partially threaded shaft made aligning with my fixture plate so much easier than fully threaded bolts. These 12.9 grade screws feel incredibly solid for the price, and the zinc coating looks clean and uniform across all 25 pieces.
