1/2-13 × 2-3/4" 馬車螺栓 | 全螺紋 | 316 不鏽鋼 (25 個/包)

The square neck grabbed the wood immediately, no spinning or cursing like I’m used to with cheaper sets. These 316s are noticeably heavier and the threads are clean all the way down, so the nut spun on smooth. I’ve got a deck rebuild coming up and already feel better about it.

After fighting with standard bolts that kept spinning, I finally tried these and the square neck grabbed instantly into the cedar—what a relief. The 316 stainless finish is noticeably smoother than the cheaper hardware I’ve used before.

These are holding down some heavy wooden posts on my deck, and that square neck really does prevent them from spinning while I tighten the nut. The smooth stainless head looks much cleaner than standard hex bolts would have.
