Jergens 215-066245 Keylocking Thread Insert M10 1.5

Product Description

The JERGENS 215-066245 is a solid keylocking thread insert designed to install a permanent, high-strength threaded hole in metal parent materials. The insert features an M10 x 1.5 internal thread and a 5/8-11 external thread, allowing it to accept metric fasteners while locking into an inch-threaded host bore. Overall length is 0.5 inches. Manufactured from C1215 carbon steel with a zinc phosphate coating, this insert resists pullout and rotation once driven into the parent material. It meets NAS 1394 standards and suits applications where thread stripping or damage has occurred or where a stronger thread is required from the start.

This insert is suited for use in production machining, maintenance repair, and tooling applications where reliable metric thread retention in steel or cast components is required. It is commonly installed in machine frames, fixtures, and structural assemblies subject to vibration or repeated fastener cycling. The solid keylocking design makes it appropriate for high-load environments where coil-type inserts may not provide sufficient retention.

Key Features

• Solid keylocking design provides positive mechanical retention against rotation and axial pullout
• M10 x 1.5 internal thread with 6H class of fit for standard metric fastener compatibility
• 5/8-11 external thread with 2A class of fit for precise engagement in the host bore
• C1215 carbon steel construction with zinc phosphate coating for corrosion resistance
• Meets NAS 1394 standard for thread locking insert performance
• 0.5 inches overall length suitable for moderate wall thickness applications

Compatibility

Designed as an OEM-style solid keylocking insert for parent materials bored to 5/8-11 thread specifications where an M10 x 1.5 internal thread is required. Compatible with Metric Coarse, UNC, and UNF thread standard applications as noted in product specifications.

Installation Notes

Installation is performed by machinists or maintenance technicians using a driver tool sized for the keylocking insert series. The parent bore must be tapped to 5/8-11 prior to installation. Keys are driven into the parent material after the insert is seated to lock it against rotation. Always verify bore depth and thread engagement before driving keys to avoid insert damage or improper seating.
