5/8-11 x 5" 馬車螺絲 | 全牙 | 316不鏽鋼 (25 / 包)

The square neck on these carriage bolts grabbed the pressure-treated lumber perfectly on my deck rebuild, no spinning at all. I used a full box for the joist hangers and railing brackets, they threaded clean and the stainless finish looks really sharp.

The square neck on these carriage bolts bit into the wood perfectly, no spinning while I tightened them down. The stainless steel feels solid and heavy, exactly what I needed for a marine environment.

Used these to fasten a heavy wooden gate to a steel frame, and the 316 stainless steel held up perfectly after a week of rain. The full threading made it easy to get a tight fit without any slipping.
