مسامير عربة 5/16-18 × 2-1/4" | ملولبة بالكامل | فولاذ مطلي بالزنك A307 Grade A (125/عبوة)

I needed these for a deck repair, and the square neck grabbed perfectly into the wood without spinning. The zinc plating looks clean and should hold up fine outdoors.

These are perfect for securing a heavy wooden gate I built — the zinc plating looks clean and the threads grabbed nicely with no stripping. I used all 125 bolts on two different projects and every single one had a clean, square seat under the head.

The square neck under the head really does bite into the wood nicely, stopping the bolt from spinning when you tighten it. I’ve got about half the box used on a pergola project so far with no stripping issues.
