مسامير عربة 5/16-18 × 2-1/4" | ملولبة بالكامل | فولاذ عادي درجة A307 (875/عبوة)

The square neck on these bolts grabbed tight into the wood as I tightened them, no spinning at all. Worked perfectly for attaching a heavy gate hinge, and the 875-count box will last me through many more projects.

I've been using these carriage bolts for a deck repair, and the square neck really does lock them in place—no spinning while tightening. The A307 grade steel feels solid, and having 875 in one package means I won't run out mid-project.

These bolts fit snugly into the pre-drilled holes on my trailer deck, and the square neck kept them from spinning while I tightened the nuts. The 875-count box is a great value for a large project.
