Tha tighten screws on my vise jaws stripped. I decided to replace the jaws. There were no references on the jaws so google led me to Discount Flies which posted a picture that looked exactly like what I needed. After talking to the owner Chris, I felt confident and ordered it. After learning curve for me to install the jaws fit and work as they should. I purchased two sets for future as my no name vise couldn’t help me.
