مسامير عربة 1/4-20 × 3-1/4" | ملولبة بالكامل | فولاذ عادي درجة A307 (550/عبوة)

I used these for a deck repair and the fully threaded shaft made installation much smoother than the partial-thread bolts I’ve fought with before. The 550-count box gives you plenty of spares for future projects, too.

The square neck on these bolts grabbed perfectly into the wood, so no need for a second wrench to tighten them. For a hardware pack this size, the plain steel finish looks uniform and clean right out of the box.

Used these for a pergola project and the fully threaded length made installation a breeze. The A307 grade steel feels solid and the square neck grabbed tight into the wood just like it should. Over 500 bolts in the pack was way more than I needed, but the price was right for the quantity.
