مسامير عربة 7/16-14 × 3 بوصة | ملولبة بالكامل | فولاذ مجلفن درجة A307 (50 / عبوة)

The square neck on these bolts grabbed perfectly into my pressure-treated lumber, no spinning while I tightened the nuts. The zinc coating seems evenly applied, and all 50 pieces came with clean threads.

Put these together on a pergola project and the smooth rounded head sits flush without snagging on anything. The zinc coating seems solid enough to resist rust after a week of rain too.

The square neck grabbed the wood instantly and held tight while I cinched everything down—no spinning or cursing. For a 50-pack at this price, the zinc coating looks even and clean, and every shaft came threaded all the way to the head. Exactly what my deck frame needed.
