براغي رأس سداسي M18-1.5 × 100 مم | فولاذ فئة 8.8 زنك أصفر | ملولبة جزئيًا (40 / عبوة)

I needed a dozen of these for mounting a heavy jig, and the 100mm length with partial threading grabbed enough bite in the steel frame. The hex heads seated perfectly with a socket—no rounded corners at all. Solid hold for the price.

Used these on a heavy-duty press jig and the 8.8 grade held up perfectly under load, no stripping. The yellow zinc finish is a nice touch for corrosion resistance, and the partial threading made alignment a breeze. Exactly what I needed for structural assembly.

These bolts handled our equipment frame assembly without a single stripped thread, and the yellow zinc coating looks properly applied across all 40 pieces. The partial threading was exactly what I needed for pulling two flanges tight together.
