Evelyn Z. ★★★★★

The unthreaded grip length on these made all the difference for aligning two steel plates without the threads chewing up the holes. Pack of 90 is plenty for a weekend project, and the hex heads seated cleanly with a standard socket.

Isabella ★★★★★

The 3/8-16 threading matched up perfectly with the nuts I already had, making assembly quick. The unthreaded grip section on these steel bolts gave me a solid, vibration-resistant connection for a shelving frame I built.

David R. ★★★★★

The partial threading is spot on—the unthreaded grip section seated perfectly through my clearance holes without any slop. All 90 bolts arrived with clean, uniform threads and the steel feels solid enough for framing work.
