مسامير نقل 1/2-13 × 2-3/4 بوصة | ملولبة بالكامل | فولاذ مطلي بالزنك درجة A307 (50 / عبوة)

The square neck under the head grabbed the wood instantly with my impact driver—no spinning or cursing like with standard hex bolts. Zinc plating looks even and the full threads bit cleanly into the pre-drilled holes. These are going to hold my deck frame together for years.

The threaded section is clean and consistent across all 50, so my wrench didn’t slip once while tightening them into the deck frame. The zinc coating looks uniform and should hold up fine against the weather here.

These bolts did a solid job on my deck repair. The zinc plating seems good and should resist rust, though I did find one bolt in the pack had slightly uneven threads.
