براغي رأس سداسي M16-1.5 × 140 مم | فولاذ فئة 8.8 عادي | خيط جزئي (25/عبوة)

I needed some heavy-duty bolts for a press jig and these M16s fit perfectly—the hex head let me torque them down solidly with a socket wrench. The class 8.8 steel feels tough enough for the job, and the partial thread saved me from having to cut them down.

The hex head grabbed my socket wrench perfectly with zero slipping, and the partial threading made aligning the joint a breeze. A solid, sturdy feel to the steel that inspires confidence in the assembly.

The partially threaded design made aligning my equipment frame much easier than using fully threaded bolts. Each hex head fit my socket wrench perfectly, though I wish the plain steel had a touch more corrosion protection for outdoor use.
