Jergens 215-065926 Thread Locking Insert 1/2-13 Unc

Product Description

The JERGENS 215-065926 is a thin wall keylocking thread locking insert designed to install a permanent, load-bearing internal thread into a parent material. It accepts a 1/2-13 UNC internal thread and installs via a 5/8-11 UNC external thread, with an overall length of 0.62 inches. The zinc phosphate coating on C1215 carbon steel provides corrosion inhibition and dimensional consistency. Machinists, maintenance technicians, and mechanical assemblers install these inserts when a host material requires a reinforced internal thread that resists rotation and pullout under vibration or torque loads.

This insert is suited for applications in industrial machinery, structural assemblies, and equipment maintenance where a standard tapped hole is insufficient. The thin wall keylocking design is appropriate when bore diameter is constrained and a full-size insert will not fit. It is commonly used in metalworking, OEM equipment manufacturing, and field repair scenarios where thread stripping is a known failure mode. Compliance with NAS 1394 makes it appropriate for aerospace-adjacent and high-specification mechanical assemblies.

Key Features

• Thin wall keylocking design conserves host material wall thickness
• 1/2-13 UNC internal thread with 2B class of fit for standard fastener engagement
• 5/8-11 UNC external thread with 2A class of fit for installation into tapped parent bore
• C1215 carbon steel construction with zinc phosphate coating for corrosion resistance
• Meets NAS 1394 standard for thread locking inserts
• Compact 0.62 inch length suits shallow boss and thin-section applications

Compatibility

Designed as an OEM-style replacement or new-installation thread locking insert for industrial assemblies requiring a 1/2-13 UNC internal thread in a 5/8-11 UNC tapped parent hole.

Installation Notes

Installation is performed by machinists or mechanical technicians using the appropriate keylocking insert installation tool to drive the locking keys into the parent material after the insert is threaded into place. The parent hole must be tapped to 5/8-11 UNC before installation. Ensure the assembly is de-energized and secured before beginning thread repair or insert installation work. Follow the insert manufacturer's installation procedure and applicable torque requirements for the fastener used with the installed insert.
