براغي رأس سداسي M20-2.5 × 220 مم | فولاذ فئة 8.8 مطلي بالزنك | ملولب جزئيًا (10 / عبوة)

I was worried the partial threading might not hold tight enough, but the hex head grabbed perfectly with a socket wrench, and the zinc plating looks clean and rust-resistant. These are exactly what I needed for mounting a heavy jig to my drill press table.

Finally got a proper M20 bolt with real thread length—the partially threaded design handled my heavy equipment bracket without any binding. Zinc plating looks clean and the hex head fits a standard wrench perfectly.

Finally, some M20 bolts that are actually the full 220mm length under the head. The hex head took a 30mm socket perfectly for torquing down on a heavy press frame.
