3/8-16 × 7" مسامير عربة | فولاذ مطلي بالزنك من الدرجة A307 (50/عبوة)

I needed longer bolts for a deck project and these 7-inchers were exactly what I was after. The square neck grabbed the wood nicely and kept them from spinning as I tightened the nuts.

The square neck on these bolts locked into the wood perfectly during my pergola build, no spinning at all. Finish is consistent across all 50 pieces, and the zinc coating looks like it'll hold up fine outdoors.

The square neck grabbed the wood instantly, so I didn't need a second wrench to hold the bolt still while tightening. All 50 of them came out of the box with a smooth, consistent zinc finish that looks clean on the pergola frame.
