براغي رأس سداسية M24-3 X 280 مم | فولاذ فئة 8.8 مطلي بالزنك | ملولبة جزئياً (2 / عبوة)

The partially threaded design made seating these against a flange much easier than fighting a fully threaded bolt, and the zinc coating took the wrench marks without chipping. These class 8.8s are solid for the price, and the hex head fit my socket perfectly.

Used these on a heavy press rebuild and the 8.8 grade held up perfectly under torque. The partial threading made alignment much easier than I expected.

The hex heads seated cleanly with a socket wrench, and the zinc plating looks uniform across both screws. The partial threading gave me just the right grip depth for the machinery bracket I was fixing, and the class 8.8 steel feels solid enough for repeated torque.
