E-z Lok 653-8 Thread Locking Insert M8 X 1.25 Stainless

Product Description

The E-Z LOK 653-8 is a standard-wall thread locking insert designed to provide a durable M8 x 1.25 internal thread in materials that require a stronger, more secure threaded connection. The insert installs with a 1/2-13 external thread and measures 0.484 inches in overall length. Constructed from 303 stainless steel with a bright finish, it resists corrosion and delivers consistent thread engagement in both metric coarse and metric fine applications. This part is suited for maintenance, repair, and fabrication work where thread repair or thread reinforcement is required in metallic or composite base materials.

The 653-8 is used in applications requiring a reliable threaded insert where the base material threads have stripped or where engineered thread reinforcement is specified from the outset. With an M8 x 1.25 internal thread class of fit 2B and a 1/2-13 external thread class of fit 2A, it fits standard tapped holes and is compatible with metric coarse and metric fine thread standards. Machinists, maintenance technicians, and industrial assembly professionals commonly install this insert in metal workpieces across light industrial and commercial equipment contexts.

Key Features

• M8 x 1.25 internal thread with class of fit 2B for consistent metric thread engagement
• 1/2-13 external thread with class of fit 2A for secure installation in standard tapped holes
• 303 stainless steel construction with bright finish for corrosion resistance
• Standard wall configuration suitable for typical wall-thickness applications
• Compatible with both metric coarse and metric fine thread standards
• Designed for use with a standard tap type for straightforward installation

Compatibility

Designed as a standard-wall thread locking insert for use in base materials tapped to accept a 1/2-13 external thread, compatible with metric coarse and metric fine thread standard applications.

Installation Notes

Installation is typically performed by machinists or maintenance technicians using a standard tap to prepare the receiving hole before driving the insert. Power down and de-energize any equipment before performing thread repair work on in-service components. Verify that the tapped hole dimensions and thread class match the insert specifications before installation to ensure proper retention and load performance.
