1/2-13 × 3-1/2" مسامير عربة | ملولبة بالكامل | فولاذ مقاوم للصدأ 316 (25 / عبوة)

The square neck seated perfectly into the wood with just a few taps, and the 316 stainless finish feels heavy-duty enough for saltwater decking. These fully threaded 3-1/2 inch bolts held firm through a windy week of framing without a single one spinning loose.

I was impressed by how smoothly the square neck pulled into the wood—no spinning or slipping during installation. The threads are deep and clean on these fully threaded bolts, which made tightening them feel solid and secure.

These carriage bolts cinched down perfectly on my new fence gate, and the square neck grabbed the wood without spinning. The 316 stainless feels substantial and should hold up well through the weather here.
