The yellow zinc coating looks even better in person, and the threading is clean all the way down, which made them easy to drive into my equipment frame without any binding. They're hefty and solid, and the hex head sat flush with my socket wrench for a tight, secure fit.

The head is tall enough that my 24mm socket grips it fully without any wobble, which made torquing these down in a tight spot much easier than I feared.
