Riley ★★★★★

The square neck on these carriage bolts grabbed the wood perfectly and didn't spin at all while I tightened the nut. I used them for a heavy-duty pergola base and they held up great, even with the 24-inch length. Nice solid feel for plain steel.

Adam ★★★★★

These bolts are exactly the right length for the heavy timber beams I'm joining, and the plain steel finish is perfectly fine for indoor framing projects.

Charlotte B. ★★★★★

The square neck under the head grabbed really well into the pressure-treated lumber I was using—no spinning at all during installation. The plain steel finish is exactly what I expected for the price, and having a full box of 40 means I have plenty left for future projects.
