مسامير عربة 1/4-20 × 2-3/4 بوصة | ملولبة بالكامل | فولاذ مطلي بالزنك A307 درجة A (200/عبوة)

The square neck on these bolts grips the wood perfectly, so they don't spin while I'm tightening them down. I used a full box to rebuild a garden planter, and every single one seated flush with no stripped threads.

Had a few loose deck boards that these bolts cinched down perfectly—that square neck really grabs tight so nothing spins. The zinc coating looks clean and held up fine through a couple of rainstorms so far.

The square neck design really locked these carriage bolts into place while I was building a new deck bench—no spinning or slipping at all. The fully threaded shaft made installation smooth, and the rounded head gives a clean, professional look.
