مسامير عربة 3/8-16 × 5 بوصات | ملولبة بالكامل | فولاذ مطلي بالزنك A307 درجة A (100 / عبوة)

I used these to build a new picnic table, and the square neck grabbed the wood perfectly so no wrench needed to hold them tight. The zinc coating looks clean and even across all 100 bolts. Exactly what I needed for the job.

The threads are clean and consistent across all 100 bolts, making assembly quick. I used them to build a heavy-duty gate and the square neck held firm without spinning.

Installed a bunch of these on my new deck railing—the 5-inch length was perfect for going through the post and into the stringer. The zinc plating seems thick enough that I'm not worried about rust after a few rain showers.
