Jergens 215-066355 Thread Locking Insert M10x1.5 Metric

Product Description

The JERGENS 215-066355 is a thin wall keylocking thread locking insert designed to create a permanent, reinforced threaded connection in metallic base materials. It accepts an M10 x 1.5 internal thread and installs via an M14 x 1.5 external thread, with a 14 mm overall length. Manufactured from 303 stainless steel with a passivated finish, this insert delivers corrosion resistance and dimensional stability in demanding environments. It conforms to NAS 1394 standards and carries an internal thread class of fit of 6H and an external thread class of fit of 6G. Maintenance technicians, machinists, and industrial assembly professionals install this insert where thread repair or thread reinforcement is required in thin-wall applications.

This insert is suited for metric coarse thread applications in aerospace, industrial machinery, and precision assembly environments. The thin wall keylocking design allows installation in applications where housing wall thickness is limited, reducing the need for a larger boss or boss redesign. It is appropriate for both new production builds and repair scenarios where a stripped or damaged M10 thread must be restored to full load-bearing capacity.

Key Features

• M10 x 1.5 internal thread with 6H class of fit for precise mating with standard metric coarse fasteners
• M14 x 1.5 external thread with 6G class of fit for secure installation into prepared host material
• 14 mm overall length suits thin-wall and space-constrained applications
• 303 stainless steel construction with passivated finish for corrosion resistance
• Thin wall keylocking design locks insert in place to prevent rotation under torque load
• Meets NAS 1394 standard for thread locking insert performance

Compatibility

Designed as an OEM-style replacement or new-installation thread locking insert for applications requiring a metric coarse M10 x 1.5 internal thread in a thin-wall keylocking configuration.

Installation Notes

Installation is performed by machinists or maintenance technicians using the appropriate keylocking installation tool. The host material must be drilled and tapped to accept the M14 x 1.5 external thread before the insert is driven in. Keys are staked into the host material after seating to lock the insert against rotation. Always de-energize and de-pressurize any associated equipment before performing thread repair or insert installation work.
