FL-M50-HI-CR

Overview

The E-Z LOK FL-M50-HI-CR is a heat-set and ultrasonic threaded insert designed for post-molding installation in thermoplastic materials. It features a straight, flanged body constructed from brass with stainless steel threads to ensure corrosion resistance and durability. The internal thread size is M5-0.8, providing a secure fastening point within plastic substrates. Key dimensional specifications include an installed length of 9.65mm and a recommended drill size of 6.40mm for proper insertion. This component utilizes ultrasonic energy for rapid, clean integration into molded parts.

Feature Summary

• Ultrasonic installation method enables rapid, clean bonding without adhesives or mechanical stress on the substrate
• Brass body provides structural integrity while stainless steel threads offer superior corrosion resistance
• Flanged design ensures precise depth control and prevents pull-through during assembly

Applications

• Post-molding insertion into thermoplastic components
• Creating durable threaded holes in soft plastics for screw attachment
• Electronics housing assembly requiring high vibration resistance

Procurement Notes

Verify that the procurement specification explicitly matches part number FL-M50-HI-CR to confirm the combination of brass body material and stainless steel threading. Ensure the application environment supports ultrasonic welding parameters compatible with this specific insert geometry. Confirm compliance requirements such as RoHS3 status if applicable to the final product assembly standards.

Selection Notes

Select this insert when post-molding installation in thermoplastics is required rather than overmolding. The choice between brass body and stainless threads addresses specific corrosion and strength needs. Verify that the target plastic material can withstand the thermal input of ultrasonic welding without deformation. Ensure the available tooling supports the specific frequency and amplitude requirements for this insert type.

Part Context

This component belongs to the E-Z Sonic™ series of threaded inserts specifically engineered for plastic applications. Unlike self-tapping inserts for metal, these are designed for thermoplastics using ultrasonic energy. The flanged style distinguishes it from plain inserts by providing a positive stop for consistent installation depth. It serves as a robust alternative to molded-in nuts in injection-molded parts.

Replacement Considerations

Direct substitutes must match the M5-0.8 thread pitch, flanged configuration, and ultrasonic installation method. Generic threaded inserts may lack the specific flute design required for efficient ultrasonic melting and bonding. Verify that any replacement maintains the same body material composition to ensure comparable thermal conductivity and corrosion performance.
