براغي ذات رأس سداسي M16-1.5 × 90 مم | فولاذ فئة 8.8 عادي | جزئي الخيوط (25/عبوة)

I needed some heavy-duty fasteners for a welding jig and these 90mm partially threaded screws did the trick. The class 8.8 steel feels solid and the hex head takes a socket wrench without any wobble. A full set of 25 was more than enough for my project.

I needed these for securing a heavy-duty machine base, and the hex head made wrenching them tight much easier than a standard bolt. The 90mm length gave plenty of reach through the assembly, and the partial thread held firm without slipping.

Threads are clean and the 8.8 grade feels solid under the wrench, no stripping on the first couple of tightenings. Only gripe is the partial threading means I had to add a washer for my application, but that's on me for not measuring. Good value for a 25-pack.
