مسامير عربة 1/2-13 × 3-1/4" | ملولبة بالكامل | فولاذ عادي درجة A307 (50 / عبوة)

I needed some sturdy bolts for a deck repair, and these carriage bolts worked perfectly. The smooth rounded head sits flush with the surface, and the square neck kept them from spinning as I tightened the nut.

The square neck on these bolts grabbed the wood perfectly when I was building a new picnic table, no spinning at all during tightening. For the price, you get a solid 50-pack of heavy-duty hardware that feels sturdier than what I've picked up at the local hardware store.

Put these on a heavy-duty gate hinge repair and the square neck grabbed perfectly—no spinning while tightening. The included nuts threaded on smoothly without jamming.
