E-z Lok 653-14 Thread Locking Insert M14 X 2 Stainless Steel

Product Description

The E-Z LOK 653-14 is a standard-wall thread locking insert designed to provide a secure threaded connection in materials that require a reinforced or repaired internal thread. The insert features an M14 x 2 internal thread and a 7/8-9 external thread, allowing it to be driven into a tapped hole to create a strong, durable mating surface. Constructed from 303 stainless steel with a bright finish, this insert offers corrosion resistance suitable for demanding environments. At 0.687 inches in length and 0.0517 pounds, it is a compact fastening solution installed by machinists, maintenance technicians, and industrial assembly professionals.

This insert is used in applications where a metric coarse internal thread must be established or restored in a base material. The standard-wall design makes it appropriate for a range of metalworking, maintenance, and repair scenarios in both light industrial and commercial settings. It is commonly installed in engine components, machinery housings, and structural assemblies where thread integrity is critical. The M14 x 2 internal thread size suits medium-to-large fastener applications typical in mechanical and industrial work.

Key Features

• M14 x 2 metric coarse internal thread for standard metric fastener engagement
• 7/8-9 external thread for installation into a prepared tapped hole
• 303 stainless steel construction with bright finish for corrosion resistance
• Standard-wall design provides reliable thread reinforcement without excessive bulk

Compatibility

Designed as an OEM-style replacement or new-installation thread locking insert for applications requiring an M14 x 2 internal thread in a 7/8-9 tapped hole.

Installation Notes

Installation is typically performed by machinists or maintenance technicians using the appropriate installation driver or tang break-off tool. The receiving hole must be tapped to 7/8-9 specifications before the insert is driven in. Ensure the work material is secured and free of chips or debris prior to installation. Follow standard shop safety practices and consult the fastener manufacturer's installation guidelines for proper seating depth and tool selection.
