مسامير عربة 5/16-18 × 3-1/4 بوصة | ملولبة بالكامل | فولاذ A307 درجة A مطلي بالزنك (100 / عبوة)

I needed these for a deck repair and the fully threaded shaft made it easy to get a tight fit with just a socket wrench. The zinc plating on all 100 bolts looked consistent with no rough edges. They held up perfectly during installation, no stripping on the heads.

The square neck design really grabbed into the wood as promised, no spinning or slipping while I tightened them. These bolts are exactly the right length for sandwiching two 2x4s together.

Needed a full set of these for a deck repair, and the zinc plating on every bolt was clean and consistent—no rust spots or flaking right out of the box. They seated perfectly into the pre-drilled holes, and the square neck grabbed tight without spinning.
