مسامير عربة | 1/2-13 × 28" | فولاذ عادي درجة A307 (35/عبوة)

The square neck grabbed instantly in the wood when I tightened the nut, no spinning at all. These 28-inch lengths were exactly what I needed to tie several 4x6 beams together on the deck frame.

I needed these for a heavy timber project and the 28-inch length was just right for going through thick beams. The square neck grabbed the wood instantly, so I didn't have to fight with a wrench to keep them from spinning.

The square neck under the head really digs in tight, so the bolts don't spin when I'm tightening them down. They're plenty long enough for my heavy timber project, and the pack of 35 gives me some extras.
