5/8-11 X 4" 馬車螺栓 | 全螺紋 | 316 不鏽鋼 (25 / 包)

The square neck on these bolts really bites into the wood and keeps them from spinning while I tighten. I used them for a heavy gate hinge, and the 316 stainless finish hasn't shown any rust after a week of rain.

Installing these on my dock was a breeze—the 316 stainless finish is noticeably smoother than the zinc-coated ones I’ve used before. They’re fully threaded, which made getting the right depth simple, and the square neck locked in place perfectly without any spinning.

The square neck on these bolts grabbed the wood immediately, so I didn’t need a second wrench to keep them from spinning. The 316 stainless steel feels solid and corrosion-resistant, which was exactly what I needed for an outdoor deck project.
