3/4-10 x 8" 馬車螺栓 | A307 A級鋼原色 (30/包)

I needed these for a heavy timber gate and the 8-inch length gave me plenty of thread to fasten through two layers of 2x8s. The square neck seated perfectly and the plain steel finish holds a coat of paint nicely.

Used these to build a heavy-duty picnic table frame, and the smooth dome head looks much cleaner than standard hex bolts. The square neck locked into the wood perfectly with zero spinning while I tightened the nuts.

The square neck grabbed perfectly into the wood on my trailer deck, so these didn't spin at all while I tightened them. I needed something strong for a heavy repair, and an 8-inch length in 3/4-inch diameter was just right.
