These bolts threaded smoothly into the frame of my press jig without any binding. The yellow zinc coating is evenly applied and looks like it'll hold up well in a shop environment.

I needed a dozen of these for a heavy equipment repair, and the hex head fit my wrench perfectly without slipping. The partial threading gave me just the right grip for the depth of the hole.

The yellow zinc coating on these Grade 5 bolts is holding up well in a slightly damp shop environment, and the partial threading made alignment much easier on a heavy equipment frame I was bolting together. They drove in smoothly with a socket wrench.
