E-z Lok 653-16 Thread Locking Insert M16x2 1-8 Stainless

Product Description

The E-Z LOK 653-16 is a standard wall thread locking insert designed to provide a strong, permanent internal thread in materials that may not hold threads reliably on their own. The insert features an M16 x 2.00 internal thread and a 1-8 external thread, allowing it to be driven into a pre-tapped hole to create a durable threaded connection. Constructed from 303 stainless steel with a bright finish, it offers solid corrosion resistance for demanding environments. The overall length is 25/32 inches (0.781 inches decimal). This type of insert is installed by machinists, maintenance technicians, and assembly professionals in metal fabrication and repair applications.

This insert is suited for use in both metric coarse and metric fine thread standard applications where an M16 internal thread is required. The 1-8 external thread drives into a standard tapped host material using the appropriate installation tool. It is commonly used in industrial assembly, equipment repair, and structural fastening scenarios where thread integrity is critical and the base material needs reinforcement. The standard wall design is appropriate for most conventional host material thicknesses and standard tap sizes.

Key Features

• M16 x 2.00 internal thread with 2B class of fit for reliable fastener engagement

Compatibility

Designed as an OEM-style replacement or new-installation thread locking insert for applications requiring an M16 x 2.00 internal thread and a 1-8 external thread in standard wall configuration, using a standard tap type for installation.

Installation Notes

Installation is typically performed by machinists or maintenance technicians using the appropriate E-Z LOK installation tool for this insert series. The host material must be tapped to the correct 1-8 thread specification before installation. Power down or de-energize any equipment before performing thread repair or insert installation on in-service machinery. Follow applicable torque and assembly guidelines from the equipment manufacturer for the fasteners used with the installed insert.
