براغي ذات رأس سداسي M22-2.5 × 180 مم | فولاذ مقاوم للصدأ 316 | خيط جزئي (5 / عبوة)

Installed these on a marine hatch where corrosion is a constant battle—the 316 stainless is exactly what I needed. The partially threaded design gave me just enough smooth shank for alignment before the threads bit. They torqued down evenly with a socket, no wobble.

The threading stops just where I need it for a clean clamp-up, and the 316 stainless took the outdoor exposure without a speck of rust. These M22s are hefty enough that I didn't second-guess the torque on our assembly jig.

These bolts handled the load on our press without any flex, and the 316 stainless is perfect for the outdoor mounting I needed. The hex head gave my impact driver a solid grip during installation.
