براغي رأس سداسي M20-2.5 × 45 مم | فولاذ فئة 8.8 مطلي بالزنك | كامل الخيوط (25 / عبوة)

The zinc plating looks clean and uniform, no flaking when I torqued them down on the machine frame. Threads ran smoothly into the tapped holes, and all 25 came out of the bag without a single defect.

Used these to bolt down some heavy shop equipment and the hex head made installation quick with a socket wrench. The fully threaded shaft gave me a solid, secure grip all the way through.

Zinc plating is holding up well on these, threads are clean all the way through, and the 45mm length was exact for my jig setup. Twenty-five pieces for this class of bolt is a fair deal, I've already used a dozen.
