FL-428-HI-CR

Overview

The E-Z LOK FL-428-HI-CR is an ultrasonic threaded insert designed for post-molding installation in thermoplastic materials. It features a straight, flanged body machined from stainless steel with a #1/4-28 internal thread size. The component requires a drill size of 0.315 inches for proper insertion and utilizes the E-Z Sonic™ technology for secure bonding within plastic substrates.

Feature Summary

• Designed for post-molding installation in thermoplastic materials using ultrasonic energy
• Constructed from high-quality stainless steel for corrosion resistance and durability
• Features a straight, flanged profile to ensure secure retention within the host material

Applications

• Post-molding threading in thermoplastic components
• Ultrasonic assembly processes requiring durable metal threads in plastic housings
• Applications demanding corrosion-resistant threaded inserts in electronic or automotive enclosures

Procurement Notes

Verify exact specifications against the official product datasheet before procurement. Confirm material grade and thread compatibility with your specific thermoplastic substrate. Ensure availability of compatible ultrasonic installation tools, such as part number HST-4, for proper deployment.

Selection Notes

Select this model when stainless steel construction is required for environmental resistance. The #1/4-28 thread size dictates the mating fastener compatibility. Verify that the target thermoplastic material is suitable for ultrasonic heat-set insertion techniques and that the 0.315-inch hole dimension aligns with your design constraints.

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 adding robust metal threads to plastic parts after the molding process, offering an alternative to traditional heat-set methods.

Replacement Considerations

The FL-428-HI serves as the brass variant of this insert family. While functionally similar in geometry and application, the material differs significantly. Substitution requires verification of corrosion requirements and thermal conductivity needs relative to the original stainless steel specification.
