Olivia ★★★★★

Used a full box on a steel frame project and every bolt seated cleanly with the zinc finish holding up nicely against scratches. The unthreaded grip section made alignment through the clevis holes noticeably easier than dealing with fully threaded hardware.

Steven ★★★★★

The partially threaded shank gave me just the grip length I needed for a steel-to-wood connection, and the zinc coating looks clean even after a few weeks in my garage. Packing was sturdy, so all 100 arrived without a single bent thread.

Jacob ★★★★★

Used these to bolt down a workbench leg that kept wobbling, and the unthreaded grip section let the bolt seat perfectly without binding in the wood. The zinc plating has held up well in my garage, no rust after a few weeks of humidity.
