Install Keensert®-style inserts.

Screw inserts into tapped holes by hand and place the tip of these tools into the insert. Strike the tools with a hammer to drive the keys into the material.

Tools that feature a spring have a knurled grip on that lets you screw inserts into tapped holes, reducing hand fatigue if you’re installing many of them. To fit over inserts evenly, tools have an inner plug and outer ring that align with keys. Strike tools with a hammer to drive keys. The spring along the shaft returns the striking end to its original position to generate more force.

Choose tools that match your insert’s thread size and tap thread size.
