مسامير عربة 5/16-18 × 7 بوصة | فولاذ A307 درجة A مطلي بالزنك (50 / عبوة)

The square neck on these bolts really digs in tight—no spinning when I'm tightening them down on my deck frame. Perfect length for sandwiching two layers of 2x6s.

I was a little worried these 7-inch bolts might be too long for my project, but the square neck pulled right into the timber and held fast without any slipping. The rounded head sits flush and looks clean, and the zinc coating on this 50-pack seems solid so far.

The square neck grabbed the wood immediately, so I didn't have to wrestle a wrench to keep them from spinning while tightening. All fifty came out of the box with clean zinc threads and no bent shafts, which is more than I can say for cheaper packs I've tried.
