Jergens 215-066113 Keylocking Thread Insert 1-1/8-12

Product Description

The JERGENS 215-066113 is a heavy-duty keylocking thread locking insert designed to create a strong, permanent internal thread in a parent material. The insert features a 1-1/8 inch-12 internal thread and a 1-1/2 inch-12 external thread, allowing it to be driven into a pre-tapped hole and locked in place using a keylocking installation tool. Once installed, the locking keys are driven into the parent material to prevent rotation and pull-out. Finished with a zinc phosphate coating for corrosion resistance, this insert is manufactured from C1215 grade steel and conforms to NAS 1394 standards. It is suited for applications requiring a reliable, high-strength threaded connection in metal assemblies.

This insert is used in industrial and manufacturing environments where standard threads in softer or worn parent materials need to be restored or reinforced. It is appropriate for machine components, tooling fixtures, and structural assemblies where thread integrity under load is critical. Licensed machinists and maintenance technicians typically install this style of insert during fabrication or repair operations. Its heavy-duty designation makes it suitable for higher-load applications compared to standard-duty keylocking inserts.

Key Features

• 1-1/8 inch-12 internal thread accepts matching fasteners directly after installation
• 1-1/2 inch-12 external thread for installation into a matching tapped parent hole
• Heavy-duty keylocking design resists rotation and axial pull-out under load
• Zinc phosphate finish provides corrosion resistance in service environments
• C1215 steel construction meets NAS 1394 standards for thread insert performance

Compatibility

Designed as an OEM-style keylocking thread insert for use in metal parent materials tapped to a 1-1/2 inch-12 external thread specification, conforming to NAS 1394 requirements.

Installation Notes

Installation is typically performed by a machinist or maintenance technician using a keylocking insert installation tool. The parent material must be drilled and tapped to the correct external thread specification before the insert is driven in. Power down and de-energize any equipment before performing thread repair or insert installation on assembled machinery. Follow NAS 1394 installation guidelines and use the appropriate key-staking tool to properly lock the insert keys into the parent material.
