مسامير نقل 5/8-11 × 8-1/2 بوصة | فولاذ عادي درجة A307 (10 / عبوة)

The square neck grabbed perfectly into the wood frame on my deck rebuild, and the 8-1/2 inch length gave plenty of bite through two layers of treated lumber. These carriage bolts feel solid and the plain steel finish is exactly what I needed for a budget-friendly, heavy-duty install.

Installed these on a heavy gate and the rounded heads gave it a really clean look. The square neck bit into the wood just as expected, holding tight without any spinning.

Those square necks grabbed the wood perfectly on my deck frame, so I didn't need a second wrench at all. The 8-1/2 inch length was just right for sandwiching two 4x6 beams together.
