مسامير عربة 5/8-11 × 4 بوصة | ملولبة بالكامل | فولاذ مطلي بالزنك درجة A307 (25 / عبوة)

These carriage bolts have the square neck that grabs into the wood perfectly, so there's no spinning when you're tightening the nut. The zinc coating looks clean and even, and the full threading made it easy to get a solid hold on a heavy gate hinge.

I needed these for a heavy-duty deck project, and the rounded head sits flush while the square neck locks tight—no spinning at all. The zinc plating looks durable and the threads were clean, making installation smooth with my impact driver.

The square neck grabbed into the wood perfectly during assembly, and every bolt was fully threaded so I could sink a nut all the way down. I used them to build a heavy-duty workbench and they haven't budged an inch.
