1/2-13 × 12" مسامير عربة | فولاذ عادي درجة A307 (50 / عبوة)

The square neck gripped perfectly into the wood when I tightened them on a new deck railing. I was surprised how consistent the threads were across all 50 bolts—no jammed nuts at all.

Installed these on a heavy gate hinge, the 12-inch length gave me enough thread to bolt through two layers of 4x4. The square neck locked in tight without any spinning.

These are beefy bolts, and the 12-inch length gave me plenty of thread to work with when building my workbench frame. The square neck grabbed the wood immediately, so I didn't need a wrench to keep them from spinning while I tightened the nuts. Good to have a full box of 50 for the price.
