I'm trying to identify this specific kind of threaded (see picture)
1) knife threads. Not serrated threads like your typical EZ Lock style threaded insert
2) *cylindrical* shank/body (NOT the tapered variety, like your typical serrated EZ lock style threaded insert)
3) hex drive
I bought a used Craftsman table saw and I am looking for an insert for using a dado head and a zero-clearance insert. I went to Sears online and they show one that looks close but says it is for a Jet brand saw.
Any suggestions where I can find the inserts or who made the saw?
