Joshua ★★★★★

The square neck under the head grabbed the wood instantly as I cinched them down, and not a single one spun on me across all 130 pieces. The threads are clean and consistent too, which made driving them with a socket a breeze.

Ruby ★★★★★

These are solidly built bolts for the price; the threads are clean and consistent across all 130 pieces, which saved me a ton of time during assembly. I had to tap a couple of them into some tight pre-drilled holes, but the square neck gripped just right and kept them from spinning.

Ruby A. ★★★★☆

The square neck on these grabbed the wood right away and didn't spin, which made install way easier than I expected. Heads are clean and the threads are consistent, though a few had light surface rust that wiped off with a cloth.
