Carr Lane Reamed-Hole Fixture Keys
Each of these Carr Lane reamed-hole fixture keys can accommodate two different table-slot sizes by rotating 90°. They should be installed in a standard 5/8" reamed hole with a concentricity of .0005" TIR or better. Secure them from below using a 1/4-20 socket-head cap screw through the counterbored hole, or from above with a 5/16-18 socket-head cap screw.
