مسامير عربة 1/4-20 × 1" | ملولبة بالكامل | فولاذ مجلفن درجة A307 Grade A (500/عبوة)

Used these to build a simple raised garden bed frame, and the square neck held perfectly without spinning while I tightened the nuts. The zinc coating looks good and should hold up well outdoors for a while.

The square neck under the head grabbed the wood immediately as I tightened them, so no spinning or cursing trying to hold the bolt still. Zinc plating looks uniform and clean across all 500, and the threads are crisp enough that a nut ran on smoothly every time.

Needed these for a small deck repair, and the zinc coating looks even and clean on every single bolt. The square neck grabbed tight into the wood right away, no spinning at all during installation. Exactly the consistent quality I was hoping for at this quantity.
