FL-124-HI-CR

Overview

The E-Z LOK FL-124-HI-CR is an ultrasonic threaded insert designed for post-molding installation in thermoplastic materials. It features a straight, flanged body machined from high-quality brass to ensure structural integrity during the insertion process. The component incorporates stainless steel threads, specifically sized at #10-24, providing superior torque and pull-out resistance compared to standard brass-threaded alternatives. This configuration supports reliable fastening applications where high mechanical strength and corrosion resistance are required within plastic assemblies.

Feature Summary

• Designed for post-molding installation in thermoplastic substrates using ultrasonic energy
• Constructed with a brass body for efficient heat conduction during installation
• Features stainless steel internal threads to enhance mechanical durability
• Straight flanged design ensures secure anchoring and alignment within the host material

Applications

• Thermoplastic housing assemblies requiring high-strength threaded connections
• Electronics enclosures needing durable mounting points
• Automotive interior components subject to vibration and torque loads
• Consumer goods manufacturing involving plastic injection molding

Procurement Notes

Verify that the specific application requires stainless steel threads rather than standard brass threads, as this variant offers different mechanical properties. Confirm compatibility with existing ultrasonic welding equipment settings for brass-to-plastic fusion. Ensure the #10-24 thread size matches the intended fastener specifications. Check packaging quantities against production volume requirements to minimize handling waste.

Selection Notes

Select this model when higher tensile strength and corrosion resistance are critical compared to standard brass-threaded inserts. The stainless steel threads provide better performance in demanding environments but may require adjusted ultrasonic parameters due to material hardness differences. Consider the brass body's thermal conductivity benefits for faster cycle times. Evaluate if the straight flanged geometry aligns with the available space and load distribution needs of the assembly design.

Part Context

This component belongs to the E-Z Sonic™ series of ultrasonic threaded inserts manufactured by E-Z LOK. These inserts are engineered specifically for integration into thermoplastic parts after the molding process. The series includes various thread sizes and body geometries, with the FL-124-HI-CR representing a specific configuration combining brass construction with stainless steel threading for enhanced performance in plastic applications.

Replacement Considerations

FL-124-HI serves as the base model without the stainless steel thread specification. Substitutes must match the #10-24 thread size, straight flanged geometry, and ultrasonic installation method. Verify that alternative brands offer comparable brass body construction and stainless steel threading to maintain equivalent torque and pull-out resistance values in thermoplastic substrates.
