18-8 Stainless Steel Key-Locking Inserts
Made of stainless steel, these inserts have good corrosion resistance. Drive the keys into the surrounding material for a more secure hold than thread-locking inserts. Use them to repair or change threads in soft metals such as aluminum. Inserts may be mildly magnetic. They’re comparable to Keensert® inserts. Installation requires a drill bit, a standard tap, an installation tool, and a hammer.
Choose inserts with a thick wall for greater strength than thin-wall inserts, or to fill a large hole.

Heavy Duty Installation Tools for Key-Locking Inserts
Install key-locking inserts, including Keensert®-style inserts. Once you screw your insert into a tapped hole, place the tip of these tools inside the insert. Strike away at the tool with a hammer to drive the insert’s keys into your material.
Choose tools that match your insert’s thread size and tap thread size.
Tools with a threaded tip or a slotted end attach to your insert, creating an easy gripping point for threading it into holes. This saves you time and effort when installing large batches of inserts. Those with a spring don’t need to be manually reset, since the spring bounces back once you strike them.
