Hi Blackdiesel I brought some from Grainger I think Elkins made them I can get you the Grainger part number on it on Monday.Dave
I have a great tool collection but after tuning air guns a few times I found my craftsman set lacking and my snap on set is standard.So I went back to hardware and bought a complete set of Elkins metric long handle $30 not to bad for made in usaOur snap on guy who works our town and towns close by has been fired, and I don't know when he will be replaced.
