براغي رأس سداسي M22-2.5 × 170 مم | فولاذ مقاوم للصدأ 316 | ملولبة جزئيًا (5/عبوة)

These 316 stainless hex bolts went on a marine railing repair and the threading was clean right out of the bag. The 2.5 pitch fit perfectly with my existing nut, and the partial threading made alignment easier. Definitely heavy-duty enough for the job.

The partially threaded design is exactly what I needed for my jig setup, and the hex head grips a socket wrench without slipping. These are hefty pieces of 316 stainless that should handle the outdoor exposure on my equipment without rusting.

Finally got the right size for a heavy equipment repair; the partially threaded design gave me plenty of grip while still allowing the joint to tighten properly. These 316 stainless hex heads didn't strip even under high torque with a socket drive.
