مسامير نقل 3/8-16 × 11 بوصة | فولاذ مطلي بالزنك درجة A307 (20 / عبوة)

Used these to build a heavy-duty swing set frame and the 11-inch length was perfect for going through 4x4 posts with plenty of thread left for the washer and nut. The zinc coating held up well during assembly, no rust issues so far.

The square neck grabbed the wood instantly on my first fence repair, so no spinning or wrestling with a wrench. Zinc coat looks clean and the 11-inch length gave me plenty of bite through the 4x4.

These 11-inch bolts were exactly what I needed for a heavy timber project, and the zinc coating looks clean and uniform. The square neck design really does help hold everything steady while you tighten the nut.
