براغي رأس مقبس M18-2.5 × 80 مم | محرك مقبس سداسي | جزئي الخيوط | فئة 12.9 من سبائك الصلب مطلي بالزنك (25 / عبوة)

The hex drive on these 80mm screws fit my socket wrench perfectly, making installation a breeze. I appreciate the partially threaded design for clamping down jig components securely.

I needed bolts that could handle heavy clamping force for a tooling fixture, and these 12.9 alloy steel screws held up perfectly without any deformation. The partially threaded design gave me just the right amount of grip length for my assembly.

The partial threading on these M18-2.5 x 80mm screws is spot-on for my jig builds, and the hex socket drive seats perfectly with my Allen key. Zinc plating looks clean and even across all 25 pieces, no flaking or burrs. Solid Class 12.9 strength that gives me real confidence under load.
