مسامير عربة 3/8-16 × 3-1/4 بوصة | ملولبة بالكامل | فولاذ عادي A307 درجة A (100/عبوة)

The square neck on these carriage bolts really sinks into the wood nicely, so they don't spin when you're tightening them down. I used them for a heavy-duty gate hinge repair, and the 100-pack gives you plenty of extras for future projects.

These bolts locked into my wooden trailer deck perfectly, the square neck grips tight and stops any spinning while you tighten the nut. The plain steel finish looks exactly right for a hardware project like this.

The fully threaded design made it easy to cut them to custom lengths for my project, which saved me a lot of hassle. The square neck grabbed nicely into the wood, though a few had slightly rough edges. Good value for the price.
