مسامير عربة 5/16-18 × 9-1/2" | فولاذ عادي درجة A307 (125 / عبوة)

Needed a bunch of these for a heavy-duty fence repair, and the 9-1/2-inch length gave me plenty of bite into the posts. The square neck seated perfectly in the pre-drilled holes, making them a breeze to tighten without spinning.

I used these to build a strong pergola frame, and the plain steel finish was exactly what I needed for welding. The 9-1/2 inch length gave plenty of bite into the treated lumber, and the square neck held tight without spinning.

The square neck on these carriage bolts really does lock into the wood perfectly—no spinning while I tightened them. Needed that exact 9-1/2 inch length for a heavy timber project, and the plain steel finish matched the rest of the hardware nicely.
