مسامير عربة مقاس 5/16-18 × 6 بوصة | ملولبة بالكامل | ستانلس ستيل 316 (50 / عبوة)

I was pleasantly surprised by how smoothly these bolts drove into the treated lumber for my deck project. The 316 stainless steel feels incredibly solid and the fully threaded design gave me a much better grip than the partially threaded ones I've used before.

The square neck on these bolts grabbed perfectly into the pressure-treated lumber I was using for a deck repair, so no spinning while tightening. The 316 stainless finish also feels sturdy and should hold up well against our coastal weather.

Used a full box to build a cedar playset frame, and every single bolt seated perfectly without spinning. The 316 stainless steel feels heavy-duty and the square neck really does prevent turning during installation. Exactly what I needed for outdoor hardware.
