براغي رأس سداسي M14-2 × 50 مم | فئة 10.9 فولاذ مطلي بالزنك الأصفر | خيط جزئي (50 / عبوة)

I needed some high-strength fasteners for a heavy equipment repair, and these class 10.9 bolts handled the torque perfectly without any thread stripping. The yellow zinc coating looks uniform and should resist corrosion well in my shop environment.

Used these with a socket wrench to bolt down a heavy workbench frame, and the partial threading made alignment much easier. Yellow zinc coating looks decent and no rust issues so far. Solid grip in the hex socket with no stripping.

Grade 10.9 steel is no joke – these hex heads took a cheater bar without a hint of rounding. The yellow zinc finish cleaned up easily with brake parts cleaner, too.
