Installation of Threaded Insert Products - Keenserts
1) Drill with a standard tap drill
2) Tap new threads with a standard tap. Note: See charts for proper size and depth.
3) Screw in the insert until it is .010-.030 (.005-.015 for Miniature Inserts) below the surface. Keys locate the proper depth.
4) Drive keys down with several hammer taps on the proper installation tool.
Drill the old screw thread out with a standard drill. Follow tables for exact dimensions. Chamfer if necessary. Tap a new screw thread with a standard tap. Follow the tables for exact dimension and depth. Turn the Keensert in the tapped hole to just below the surface of the piece. Drive the keys through the Keensert. Do this by knocking with a hammer on the Keensert installation device.
Use a standard drill to remove the insert material between the keys and the internal thread, upon the correct depth (consult the tables). Deflect keys inward and break off. Remove the insert with Drill Out E-Z out tool or an equal device. An identical insert can now be installed in the original hole. No re-work of the hole will be necessary.
