5/8-11 X 14" 馬車螺栓 | A307 A級普通鋼 (25個/包)

I just used a few of these on a deck project and the smooth rounded heads sit flush without snagging anything. The 14-inch length easily punched through thick beams and the square neck held tight without spinning. They feel solid enough for heavy framing work.

The square neck grabbed perfectly into the wood on my new gate, and the 14-inch length was just right for the thicker posts. These plain steel bolts feel solid and should hold up well once painted.

I needed these for a deck repair and was impressed how easily the square neck seated into the wood without spinning. The 14-inch length gave me plenty of reach for thick beams, and the plain steel finish looks clean and solid.
