I have had my workmate for well over 20 years. (at least i think it is a workmate. All identifcation has long since worn off)
The top finally gave way and I am replacing it with new wood.
The question is .. has anybody seen this type of screw before and if so what is it called?
I can use different bolts/screws for the replacement. I just have never seen this type before.
