مسامير عربة 1/2-13 × 7 بوصة | فولاذ مقاوم للصدأ 316 (25 / عبوة)

Needed some heavy-duty fasteners for a saltwater dock repair, and the 316 stainless steel on these carriage bolts gave me real peace of mind against corrosion. The square neck under the head grabbed nicely into the wood, stopping any spinning during installation.

Installed these on a heavy wooden gate and the 316 stainless is already proving its worth after a week of rain. The smooth, rounded head sits flush without snagging, and the full 7-inch length gave me plenty of grip in the thick timber.

The square neck grabbed perfectly into the pressure-treated lumber I was working with—no spinning at all. These 316 stainless bolts feel heavy and solid, exactly what I needed for an outdoor gate hinge.
