براغي رأس سداسي M16-2 X 85mm | فولاذ من الدرجة 8.8 مطلي بالزنك | خيط جزئي (25/عبوة)

Used these to secure a heavy-duty jig on my workbench, and the hex head held up perfectly under torque from my socket wrench. The zinc plating seems solid, no rust after a few weeks in my damp garage shop. Exactly what I needed for a firm, reliable fastening.

The partial threading made installation into my existing machinery frame much easier, and the zinc plating looks like it will hold up well against rust in my shop. These 85mm screws are solid for heavy-duty use, no stripping issues with a socket wrench.

The hex head seated perfectly in my socket wrench, and the 85mm length gave just enough thread for the heavy machinery bracket I was bolting together. These class 8.8 screws feel solid for the price—no stripping or bending under torque.
