مسامير نقل 5/16-18 × 8 بوصة | فولاذ عادي درجة A307 (50/عبوة)

I was pleasantly surprised by how smoothly the square neck seated into the wood, keeping these bolts from spinning while I tightened them. Each one measures a full 8 inches, which gave me plenty of length for a sturdy connection. Definitely worth the price for a bulk pack.

These bolts were perfect for building a heavy-duty swing set, and the 8-inch length gave me plenty of bite into the pressure-treated beams. The smooth, rounded heads look much cleaner than standard hex bolts.

The square neck under the head grabbed the wood really well as I tightened them, and the plain steel finish is exactly what I needed for my indoor project. These 8-inch bolts have plenty of length for thick assemblies, and the pack of 50 should last me through several builds.
