مسامير عربة 5/8-11 × 8 بوصة | فولاذ عادي درجة A307 (10/عبوة)

These bolts fit perfectly into the pre-drilled holes for my deck railing, and the square neck grabs tight so nothing spins when I'm wrenching the nut. The plain steel finish is about what you'd expect from a workhorse fastener, but they held up fine during assembly.

The square neck really grabs hold as you tighten it, which saved me from having to use a wrench to keep it from spinning. For the price, you get solid plain steel bolts that do the job.

I used these for a deck repair and they did the job, though the plain steel is already showing some surface rust after a few weeks. The square neck pulled into the wood effectively, but I wish the heads had a bit more grip.
