براغي رأس سداسي M16-1.5 × 150 مم | فولاذ فئة 8.8 عادي | ملولب جزئيًا (25 / عبوة)

These bolts feel rock solid in hand, and the 8.8 grade steel is exactly what I needed for heavy equipment assembly. The hex head grabbed my wrench cleanly with no rounding, and the 150mm length gave just the right reach for my mounting brackets.

The partial threading on these M16 bolts made aligning my equipment frame so much easier, and the hex heads gripped the wrench firmly without any slippage. For the price of a 25-pack, the Class 8.8 steel feels solid enough for heavy shop use.

These are exactly what I needed for a heavy equipment assembly job. The 150mm length with the partial threading gives just the right grip for thick flanges, and the 8.8 steel feels solid without being brittle. No stripped heads even with a breaker bar.
