Jaws for Harbor Freight 2-1/2" Table Vise
I made these jaws to fit this table vise: https://www.harborfreight.com/2-1-2-half-inch-table-swivel-vise-97160.html
It has the same holding provisions (apparently for rounds, hexes, and squares) as the original.
The original screws can be used to attach the jaws. However, I recommend replacing the original screws. I found that M4x8 socket head cap screws fit my vise and are much easier to take in and out with ball end hex keys than the originals with a screwdriver, due to the angle you need to clear the other jaw.
Two versions are provided: One which attempts to reproduce the gripping surface of the original (this is not terribly effective), and one which is simply flat.
