براغي رأس سداسي M16-2 × 85 مم | فئة 8.8 فولاذ عادي | ملولبة جزئيًا (180/عبوة)

The 85mm length is exactly right for the layered steel brackets I’m bolting together, and the hex heads grab a socket without any slippage. All 180 pieces arrived with the partial threading consistent, which made the assembly job go much faster than I expected.

The threads are clean and the partial threading grabbed perfectly on my fixture plate—no chasing needed. For the price per box of 180, these class 8.8 bolts are a solid deal for everyday jig building.

I needed high-strength bolts for a heavy equipment frame, and these 8.8 steel caps fit perfectly with the hex wrench. The partial threading saved me time aligning the shank in tight spots.
