مسامير عربة 7/16-14 × 5 بوصة | خيط كامل | فولاذ مطلي بالزنك A307 Grade A (25 / عبوة)

The square neck under the head really digs in and keeps the bolt from spinning while you tighten it. These 5-inch A307 grade bolts are solid for heavy wood-to-wood connections. My only tiny wish is that the zinc coating was a shade thicker, but they still held up fine on my outdoor shed project.

The fully threaded length was exactly what I needed for a beefy deck repair. The square neck locked into the pressure-treated lumber firmly without any spinning.

The square neck grabbed the wood instantly on my deck project—no spinning, no wrestling with a wrench to hold it steady. Zinc plating looks clean and should hold up fine outdoors.
