مسامير عربة 5/8-11 × 11 بوصة | فولاذ عادي درجة A307 (25/عبوة)

I needed heavy-duty fasteners for a timber project and these carriage bolts did not disappoint—the square neck under the head really did grab the wood and kept the bolt from spinning while I tightened it.

These bolts are solid and the 11-inch length gave me plenty of thread for a heavy timber frame project. The smooth head sits flush without snagging, and the square neck held tight as I tightened the nut.

These bolts are massive and the square neck really does lock into the wood perfectly, no spinning at all. Used them to build a heavy-duty workbench frame and they held up great during assembly. Exactly what I needed for the price.
