ATLAS SELF ALIGNING INSERTS
Atlas self aligning inserts are precision machined for thread concentricity and uniformity. The self aligning inserts have a .450" +/- .001 barrel diameter (with glue grooves) for installation into a bored hole, and a 7/16-20 OD thread for installation.
Note: The QINSSA 14 will NOT work with the QBRPIN 14 brass bullet nosed pins.
