M12-1.75 X 180mm براغي رأس سداسي | فولاذ مقاوم للصدأ 316 | خيط جزئي (10 / عبوة)

Installed these on a stainless steel marine railing where corrosion resistance was critical, and the 316 material shines in saltwater conditions. The partial threading made alignment much easier than fully threaded bolts would have.

The partially threaded design made aligning the frame much easier, and the 316 stainless shows no rust after a week of outdoor exposure. Wrench grip on the hex head is solid, no stripping even with a cheater bar.

Installed these on a trailer hitch build and the 316 stainless finish is flawless — no rust spotting after a week of rain. Partially threaded grip is spot on for the depth I needed. Only wish they came in a bigger pack, but the price per piece is fair.
