E-z Lok 550-006 Thread Locking Insert 6-32 Internal M6 X 1

Product Description

The E-Z LOK 550-006 is a standard wall thread locking insert designed to provide a secure threaded connection in assemblies where vibration or torque load could otherwise loosen a fastener. It accepts a 6-32 internal thread and installs via an M6 x 1.00 external thread, making it suitable for applications that bridge inch and metric thread standards. Manufactured from C12L14 carbon steel with a smooth, rolled finish, this insert measures 0.2559 inches overall length (6.50 mm). Licensed tradespeople and assembly technicians install these inserts using a standard tap to prepare the receiving hole before driving the insert into place.

This insert is used in light to medium-duty metal assemblies where a permanent, vibration-resistant threaded connection is required. The standard wall design suits applications in structural brackets, enclosures, machinery frames, and similar components where hole wall thickness is sufficient to accommodate a full-thread engagement. The 6-32 internal thread accommodates standard inch-series machine screws, while the M6 x 1.00 external thread installs into a metrically tapped receiving hole, offering flexibility in mixed-thread assembly environments.

Key Features

• 6-32 internal thread with 2B class of fit for reliable inch-series fastener engagement
• M6 x 1.00 external thread with 2A class of fit for installation into a metric-tapped hole
• C12L14 carbon steel construction provides strength and machinability in standard-load applications
• Standard wall design installs using a standard tap - no specialty tooling required
• Smooth, rolled finish on external thread surface for consistent installation torque
• Compact 0.2559 inch (6.50 mm) length suits tight-clearance assemblies

Compatibility

Designed as an OEM-style thread repair and thread conversion insert for metal assemblies requiring a 6-32 internal thread installed via a standard M6 x 1.00 tapped hole. Compatible with UNC and UNF thread standard applications.

Installation Notes

Installation is typically performed by machinists, maintenance technicians, or assembly professionals. Before installation, prepare the receiving hole with a standard M6 x 1.00 tap to the depth specified for full thread engagement. Drive the insert using the appropriate E-Z LOK installation tool to avoid cross-threading or over-driving. Ensure all chips and debris are cleared from the tapped hole before inserting to maintain proper thread engagement and holding strength.
