Hazel O. ★★★★★

I needed some truly heavy-duty fasteners for a piece of farm equipment, and the partially threaded design on these Grade 8 steel bolts made them much easier to seat before torquing down with a socket. The hex head grabbed my wrench cleanly without any rounding.

Jacob M. ★★★★★

The threading is clean enough that they spin on smoothly with a socket, and the zinc finish has held up fine in my shop so far. Grade 8 rating gives me peace of mind for the load they're carrying, and the partial thread makes alignment a lot easier.

Violet ★★★★★

I've been using these for mounting heavy equipment on a steel frame, and the partially threaded design made alignment much easier. The zinc coating on the grade 8 steel looks solid and hasn't shown any rust after a few weeks of outdoor use.
