براغي رأس سداسي M18-2.5 × 100 مم | فولاذ فئة 10.9 مطلي بالزنك الأصفر | ملولبة جزئيًا (20 / عبوة)

The threads are clean and the yellow zinc finish looks uniform across all 20 pieces, which is exactly what I needed for a heavy equipment frame I'm bolting together. The partial threading on these M18s makes alignment a lot easier when you're working blind behind a mounting plate.

Pulled one of these out of the pack yesterday for a 2-ton press rebuild, and the threads engaged perfectly with an M18 die. The yellow zinc finish feels tough, and the partial threading made it easy to start by hand before torquing.

Needed a heavy-duty bolt for a press build, and these M18 screws fit the bill perfectly. The yellow zinc coating seems tough and the hex head grabbed my socket securely without any rounding.
