Innovative Components AN6C-5S421 2.25" Star Knob thru hole 3/8-16 steel zinc insert black pp (Pack of 10)

Does exactly what I needed, in a handsome and practical way. The finish is a matte black, incidentally, which was not clear from the photo posted online.

These are basic lightweight knobs. The threaded insert looks like a standard hex nut molded into the back of the knob. The knob rides fairly close to the surface, which limits how well you can grab it...this isn't the style if you really need to torque something down.

Product as described. It's a little small, height wise, but that was perfect for what I needed.

Nice large, easy to grip knobs. Clean, well cut thread pattern makes positive threading onto the bolt of your choice.
