مسامير عربة 1/4-20 × 6-1/2" | فولاذ عادي درجة A307 (425 / عبوة)

The square neck on these bolts grabbed the wood immediately, no spinning while I tightened them down. A full box of 425 means I have plenty left over for the next project.

The 6-1/2 inch length was exactly what I needed for sandwiching thick lumber together, and the plain steel threads cut cleanly without binding.

After spending a whole afternoon building a heavy-duty workbench, I'm relieved these 6.5-inch carriage bolts threaded perfectly into my pre-drilled holes without any stripping. The square neck grabbed the wood just like it's supposed to, and the plain steel finish gives a solid, no-nonsense feel.
