مسامير عربة 3/4-10 × 14" | فولاذ عادي A307 درجة A (25 / عبوة)

The square neck on these carriage bolts did exactly what it's supposed to—pulled tight and didn't spin while I tightened the nut on a heavy swing set frame. The 14-inch length gave me plenty of grip through thick treated lumber.

Went through all 25 installing a deck frame and not a single one spun on me, the square neck grabs the wood exactly as it should. The 14-inch length gave plenty of bite through the 4x4 posts, and the plain steel finish is fine for indoor work.

The square neck under the head seated perfectly into the wood on my trailer deck rebuild, and not a single one spun while I torqued them down. At 14 inches long, these A307 grade bolts have serious heft and the plain steel finish is exactly what I expect for outdoor framing work.
