1/2-13 × 2-3/4" مسامير عربة | ملولبة بالكامل | فولاذ عادي A307 درجة A (275 / عبوة)

The square neck grabbed the wood perfectly when I tightened them down, and the threads were clean all the way through the box. These bolts felt solid driving into pressure-treated lumber, and having 275 in one package saved me a trip back to the hardware store.

I needed these for a deck repair and the fully threaded length made it easy to secure the boards without worrying about stripping. They seated nicely into the wood and the square neck kept them from spinning as I tightened the nuts. A solid buy for the price.

The square neck under the head grabbed tight into the wood without spinning, and the plain steel surface was consistent across all 275 pieces. Got my entire pergola project bolted together in one go, and every driver bit engaged cleanly without stripping.
