مسامير عربة 3/4-10 × 20" | فولاذ عادي درجة A307 (20/عبوة)

Finally got my hands on these and the 20-inch length was spot-on for the heavy timber frame I'm building. They drove in straight without the head snapping, which is exactly what I needed.

These 20-inch bolts are hefty; the square neck under the head really does grab into the wood and prevents spinning. For heavy timber projects, they feel solid and well-made, though the plain steel will need a coat of paint or oil to keep rust away.

These are great for heavy-duty fence repairs, and the 20-inch length gives plenty of reach through thick beams. The plain steel finish is fine for indoor use, but I wish they were galvanized for outdoor projects.
