براغي رأس سداسي M16-2 × 400 مم | فولاذ عادي فئة 10.9 | خيوط جزئية (3 / عبوة)

These M16 bolts are exactly what I needed for a machinery mount—the partially threaded design gave me plenty of grip while still leaving room for spacers. The hex heads seated perfectly with a standard socket, and the 10.9 steel feels rock solid. Three in a pack is a fair deal for the price.

Used these to bolt down a heavy-duty press in the shop, and the 10.9 grade steel held perfectly under full load with zero stretch. The hex head made torquing them down easy with a standard wrench.

The hex head grabbed my socket wrench perfectly and the 400mm length was exactly what I needed for that heavy machinery tie-down. Class 10.9 steel feels properly solid, and the partial threading made alignment a lot easier than I expected.
