Sebastian ★★★★★

The square neck grabbed the wood immediately on my first test fit, so no spinning or wrestling with a wrench. For the price, getting 150 of these fully threaded A307 bolts means I've got plenty left for the next project.

Jacob K. ★★★★★

Installed these on a heavy wooden gate and the square neck seated perfectly to stop any spinning during tightening. The 150-count box was more than enough for the whole project and then some.

Emily ★★★★★

The square neck on these bolts grabbed the wood perfectly during my deck repairs, and the 2-1/2 inch length was ideal for sandwiching two 2x6s. A full 150-count package means I have plenty left for future projects.
