مسامير عربة 5/16-18 × 2-1/2 بوصة | ملولبة بالكامل | فولاذ عادي A307 درجة A (800 / عبوة)

The smooth rounded head sits flush without catching on anything, and the square neck grips the timber so well I didn't need a second pair of hands. The fully threaded shaft made tightening up the whole deck frame a quick job. These are solid, dependable bolts for a fair price.

Needed these for a pergola build and the fully threaded shaft was a real time-saver for stacking washers and nuts. The square neck seated perfectly in the pre-drilled holes so I didn't need a second wrench to keep them from spinning.

These bolts fit perfectly into the pre-drilled holes on my trailer deck, and the square neck grabbed the wood tight so nothing spun while I tightened the nut. For the price, having 800 of them means I can finish the whole project and have plenty left over.
