براغي رأس مقبس M16-2 × 70 مم | محرك مقبس سداسي | جزئي الخيط | فئة 12.9 سبيكة فولاذ مطلية بالزنك (25/عبوة)

I’ve been using these 70mm socket cap screws for a jig I’m building, and the Class 12.9 alloy steel feels much tougher than the usual hardware store stuff. The zinc plating gives them a clean, corrosion-resistant finish, and the partially threaded design held securely during testing.

The hex socket drive on these M16 screws makes torquing them down in tight spots a breeze, and the zinc plating looks clean and uniform across all 25 pieces. They’ve held up perfectly so far in my fixture build, where the 12.9 alloy steel really shows its strength under load.

Finally, a bolt that fits our jig frame without slop. The hex socket drive made installation easy with a simple hex wrench, and the zinc plating looks clean even after a week in our shop.
