Jergens 215-065967 Keylocking Thread Insert M10x1.5

Product Description

The JERGENS 215-065967 is a heavy-duty keylocking thread locking insert designed to create a permanent, load-bearing threaded connection in base materials. The insert accepts an M10 x 1.5 internal thread and installs via an M16 x 1.5 external thread, with an overall length of 0.63 inches (16 mm). Manufactured from C1215 carbon steel with a zinc phosphate coating, it meets NAS 1394 standards and provides a secure thread anchor in metal workpieces where thread stripping or pullout is a concern. Installation requires a keylocking driver that drives locking keys into the host material to prevent rotation.

This insert is suited for industrial, aerospace, and heavy mechanical applications where vibration or high tensile loads could compromise standard threaded fasteners. It is typically installed in machined metal components requiring a reliable metric coarse internal thread in a larger-diameter bored hole. Machinists, maintenance technicians, and assembly professionals use this style of insert to restore or upgrade thread integrity in production and field repair scenarios.

Key Features

• M10 x 1.5 internal thread with 6H class of fit for precise thread engagement
• M16 x 1.5 external thread with 6G class of fit for controlled installation fit
• Heavy-duty keylocking design resists rotation and pullout under vibration and high loads
• C1215 carbon steel construction with zinc phosphate coating for corrosion resistance
• Meets NAS 1394 standard for thread insert performance
• Metric coarse thread standard, 16 mm overall length

Compatibility

Designed as an OEM-style keylocking thread insert for metal workpieces requiring an M16 x 1.5 installation bore and delivering an M10 x 1.5 internal threaded connection per NAS 1394.

Installation Notes

Installation is performed by a machinist or maintenance technician using a dedicated keylocking insert installation tool to drive the locking keys into the host material after the insert is threaded into the prepared bore. The host material must be drilled and tapped to the correct M16 x 1.5 specification before insert installation. Ensure the workpiece is secured and de-energized from any powered system before beginning thread repair or installation work. Follow the insert manufacturer's installation procedure for key-driving depth to achieve full locking engagement.
