براغي رأس سداسي M20-2.5 × 180 مم | فئة 8.8 من الصلب المطلي بالزنك | ملولبة جزئيًا (10 / عبوة)

The partially threaded design made all the difference when I needed to clamp two thick steel plates together without the threads chewing into the mating surface. Zinc plating looks clean and the 8.8 grade feels solid under the wrench.

These hex bolts handled the high-torque job on my press assembly without stripping or flexing, the zinc coating is holding up well so far. The class 8.8 rating gives me real confidence in the build quality.

The partially threaded design was perfect for our assembly jig—the smooth shank seated cleanly while the M20-2.5 threads bit deep. Zinc plating looks uniform and held up fine against a light oil spray. These bolts feel solid, definitely worth the price for a 10-pack.
