Emma B. ★★★★★

Installed these on a new deck build and the square neck grabbed perfectly into the wood, so no spinning or slipping during tightening. The 6-1/2 inch length gave just enough thread for a nut and washer on a 2x6 board.

Christopher W. ★★★★★

These are longer than the ones at the big-box store, and the 6-1/2" length gave me plenty of thread for a thick deck post repair. The square neck seated firmly into the wood so I didn't need a second wrench to stop them spinning.

Jacob U. ★★★★★

The square neck under the head grabbed nicely into the wood, just like it should, and all 20 bolts in the package had clean, consistent threads. I used them to secure a heavy gate and haven’t had any slippage at all.
