مسامير عربة 3/8-16 × 2 بوصة | كاملة الخيوط | فولاذ مطلي بالزنك درجة A307 (150 / عبوة)

Installed these on a heavy wooden gate, and the square neck grabbed the wood perfectly so I didn't need a second wrench to hold them. The zinc plating looks clean and hasn't shown any rust after a rainy week.

I used these to build a new deck railing, and the zinc plating on all 150 bolts looked clean and uniform with no rust spots. The rounded head sits flush against the wood, giving it a nice finished look.

The square neck on these carriage bolts grabbed the wood perfectly, no spinning while I tightened them down. They’re exactly the right length for my pergola brackets and the zinc coating seems durable.
