5/16-18 X 1-1/4 英吋 馬車螺栓 | 全螺紋 | A307 等級 A 鍍鋅鋼 (250/包)

These came in a sturdy little box and the zinc plating looks even and bright across all 250 pieces. I've been using them for a fence repair and the fully threaded shaft makes it easy to get a nut on from the back side.

The square neck under the head grips the wood right away, so I didn’t have to hold the bolt in place while tightening—that alone saved me a ton of fiddling. Zinc plating looks clean and uniform across all 250 pieces, and the threads ran smooth through my pre-drilled holes.

These bolts have a smooth, rounded head that looks much cleaner than a standard hex bolt for outdoor furniture. The threads are crisp and caught easily on the nut without any cross-threading. Exactly what I needed for a sturdy repair.
