براغي غطاء رأس سداسي M8-1.25 × 120 مم | فئة 8.8 فولاذ زنك أصفر | ملولب جزئيًا (50 / عبوة)

Used these to mount a heavy steel bracket onto a concrete pillar, and the 8.8 hardness held without any stretch. The partially threaded shank made alignment a lot easier than a fully threaded bolt would have.

Needed a class 8.8 bolt for a heavy machinery repair and these hex heads fit the socket perfectly without slipping. The yellow zinc coating looks solid, too, and the partial threading made alignment a breeze.

These bolts fit perfectly in my steel brackets, and the partial threading made alignment much easier. The hex head grabbed nicely with a socket wrench, no stripping.
