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.
Black-Phosphate Steel Key-Locking Inserts
A black-phosphate finish provides mild 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. 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 with stripped threads.
Key-Locking Inserts with Installation Tool
Drive the keys into the surrounding material for a more secure hold than thread-locking inserts. These inserts are used to repair or convert threads in soft metals such as aluminum. They’re comparable to Keensert® inserts.
Black-phosphate steel inserts are mildly corrosion resistant.
Choose inserts with a thick wall for greater strength than thin-wall inserts, or to fill a large hole.

Adapters for Flexible Plastic Conduit
Tabs on one end snap into grooves in conduit; the other end attaches to a knockout in an outlet box or enclosure. These adapters help seal out air and liquid when used with flexible plastic conduit. All meet IP68 for prolonged submersion and IP69K for high-pressure, high-temperature washdowns. They withstand vibration, are flame retardant, and resist oil, solvents, and UV light.

Fittings for Shielded Flexible Plastic Conduit
These adapters provide electromagnetic interference (EMI) protection when connecting shielded flexible plastic conduit to a knockout in an outlet box or enclosure. Twist the compression end over the conduit; tighten the compression ring to secure.
A brass locknut is required (not included) when installing in an unthreaded knockout.
