1/4-20 X 1英吋 馬車螺栓 | 全螺紋 | A307 Grade A 普通鋼 (2875顆/包)

Used a handful of these to build a sturdy outdoor planter box, and the square neck really kept them from spinning as I tightened them down. They seated flush and haven't budged since; for the price per pack this is a great deal.

That square neck grabbed the wood the second I threaded the nut on, so I didn't have to wrestle a wrench to keep the head still. The fully threaded shaft made it easy to trim them down with a hacksaw and they arrived oiled enough to not rust. Exactly what I needed for a heavy gate frame.

I needed a solid hold for a planter bench I was building, and the square neck on these bolts really did grab the wood without spinning. They're plain steel, so I'll seal them, but the threads were clean and started easily by hand. A full box of 2875 will last me years.
