Ergonomic Knob 5/16" by 18 TPI 2-3/8" in diameter.
happy so far.
I bought these to replace the wingnuts i was using to lock down my router table fence and I`m happy with them so far. 4 stars is because i just haven`t used them for very long so we shall see how long they hold up. It`s a pretty minor investment though so i`m not too worried. They work just as they should.
