3/8-16 × 2-1/4 بوصة مسامير عربة | كاملة الخيوط | فولاذ A307 درجة A مطلي بالزنك (100 / عبوة)

The square neck on these bolts grabbed into the wood perfectly as I tightened them, no spinning at all. The zinc plating looks clean and should hold up fine for my outdoor bench project.

These are exactly the size I needed for a swing set repair, and the fully threaded shaft gave me plenty of grip through thick lumber. The zinc plating held up fine against a couple days of rain while I finished the job, too.

Finally a pack of fully threaded carriage bolts that actually drive in square and hold tight. The zinc plating on these looks even and clean, no flaking so far. Perfect for the heavy shelf brackets I was building.
