براغي رأس سداسي M16-1.5 X 160mm | فولاذ فئة 10.9 عادي | خيط جزئي (60 / عبوة)

Tightened down a heavy bracket on my tractor with these and the 10.9 steel held firm without any flex. The partial thread gave me just the right grip length, and they’re exactly 160mm as listed.

The hex heads grabbed my socket wrench cleanly without any stripping, and that 10.9 steel feels seriously solid for the price. I used them to bolt down a heavy equipment frame and the partial threading seated perfectly against the load.

The partially threaded design made these perfect for bolting down a heavy workbench. I’ve used a lot of grade 8 bolts before, and these 10.9 steel screws feel just as solid for the job.
