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

The zinc plating on these carriage bolts looks even and clean, no rough edges to worry about. I used them to fasten a wooden bench frame and the square neck locked in tight, just as expected. For the price, getting fifty fully threaded 1/2-13 by 3-inch bolts feels like a solid deal.

The square neck seated perfectly into the wood on my first try, and the zinc plating looks clean and uniform across all 50 bolts. Threads ran smooth with a wrench, no binding or rough spots. Exactly what I needed for a sturdy deck repair.

The square neck under the head grabbed the wood instantly and held tight while I tightened the nut, no wrench needed on the top side. Zinc coating looks clean and uniform across all 50 pieces, and the threading was smooth all the way down on every bolt I used.
