Michael W. ★★★★★

Replaced a rotted deck board and these bolts set perfectly flush, the square neck bit into the wood so they didn't spin while I tightened the nut. All 50 came clean and the threads were sharp, so I didn't strip a single one.

Robert A. ★★★★★

The square neck design really grabs into the lumber and keeps these from spinning while you tighten them. All fifty bolts were cleanly threaded and free of any burrs, which made the job go smoothly.

Lily ★★★★★

These bolts pulled tight into the wood perfectly thanks to that square neck, and the plain steel finish is a solid choice for indoor furniture projects. I used them to secure some heavy workbench legs and they haven't budged.
