The tool post holder originally had a allen bolt to secure it to the compound slide, I replaced it with a grade 8 hex bolt which made it much nicer to use. The nut on the bottom was a round aluminum nut which would slip when tightening, I replaced it with a steel nut milled to fit the compound slide. The silver aluminum holders are made from 6061 aluminum.
