Andrew ★★★★★

The square neck under the head grabbed the wood immediately once I wrenched them down, so no spinning or cursing. For a plain steel bolt, the threading is surprisingly clean across the full 3/4 inch. Bought the big package and they all came out of the box straight, which is more than I can say for s

Daniel ★★★★★

These are exactly what I needed for a bench repair, and the square neck design really locks into place when you tighten the nut. A full 3250 count means I won't run out halfway through the job.

Natalie I. ★★★★★

The square neck grabbed the wood instantly when I tightened the first one—no spinning or cursing like with cheaper bolts. The plain steel finish is exactly what I needed for a rustic project, and the fully threaded length made quick work of the assembly.
