David ★★★★★

The square neck grabbed tight into the wood as I tightened them, no spinning at all even with a heavy load. These 12-inch bolts held a big timber frame together solidly, and the zinc coating looks like it'll resist rust well.

Grace ★★★★★

The square neck on these bolts gripped perfectly into the wood beams during my deck repair, so they didn't spin at all while I tightened the nuts. The zinc coating seems thick and even, which should hold up well outdoors. I'm glad I got the 12-inch length for my heavier framing connections.

David ★★★★★

Used these to build a heavy-duty garden gate and the 12-inch length gave plenty of bite into the post. The square neck under the head really did grab tight and kept them from spinning as I tightened them.
