مسامير عربة 5/16-18 × 3/4 بوصة | فولاذ مطلي بالزنك (1000 / عبوة)

The square neck grabbed the wood instantly and didn’t spin a millimeter while I torqued them down—that zinc coating also means zero rust after a week of rain on the fence. A thousand pieces is a lot, but at this price I’d rather stock up than run short mid-project.

I've been using these carriage bolts for a few weeks now on various metal shelving projects, and the zinc plating has held up nicely without any rust. The square neck under the head grips the material perfectly so they don't spin while tightening.

Needed exactly 1000 of these for a trailer build, and every bolt seated cleanly in the square hole without any burrs. The zinc coating has a smooth, even look that matches the price point well.
