براغي ذات رأس أسطواني M22-2.5 × 45 مم | محرك سداسي | ملولبة بالكامل | فولاذ سبائكي فئة 12.9 مطلي بالزنك (10 / عبوة)

The hex socket drive makes installation really straightforward, and the zinc plating on these screws already looks like it will hold up well in my workshop jigs. I’m glad I went with the 12.9 alloy steel for the extra strength they bring to precision assemblies.

Fitted these on a custom tooling fixture and the hex drive seated perfectly with a ball-end Allen key—no stripping even under heavy torque. The 12.9 alloy steel feels rock solid, and the zinc plating gives them a clean, corrosion-resistant finish. Fast shipping too, which never hurts.

These bolts are perfect for my heavy-duty jig; the Class 12.9 alloy steel feels incredibly strong and the threads cut cleanly. I've already ordered another pack for a tooling project.
