براغي رأس سداسية M16-1.5 × 75 مم | فولاذ فئة 8.8 غير مطلي | ملولبة جزئيًا (25 / عبوة)

Used these to bolt a workbench frame together and the partially threaded shaft gripped perfectly. The class 8.8 rating gives me confidence they'll hold up under daily shop abuse.

I needed some heavy-duty fasteners for a steel frame project and the 8.8 grade on these feels plenty sturdy. The partially threaded shaft makes them easy to start by hand before tightening with a wrench. Exactly what I was hoping for.

Used these for mounting some heavy brackets in my shop, and the partial threading made installation much easier in tight spots. They held torque well without stripping. Only wish the package came with a few more for the price.
