FL-440-HI-CR

Overview

The E-Z LOK FL-440-HI-CR is a heat-set threaded insert designed for thermoplastic substrates. It features a straight, flanged body with stainless steel threads and a #4-40 internal thread size. The component requires a drill size of 0.157 inch for installation. It supports both ultrasonic and heat driver installation methods to ensure superior torque and pull-out resistance in plastic applications.

Feature Summary

• Straight flanged design for secure embedding in thermoplastics
• Stainless steel threading for corrosion resistance
• Compatible with ultrasonic or heat stake installation processes

Applications

• Thermoplastic housing assembly
• Electronics enclosures requiring durable metal threads
• 3D printed parts needing reinforced fastening points

Procurement Notes

Verify the specific datasheet for the FL-440-HI-CR variant to confirm material composition and dimensional tolerances. Ensure compatibility with existing tooling for ultrasonic or heat installation. Cross-reference the #4-40 thread specification with mating hardware requirements before finalizing procurement orders.

Selection Notes

Select this insert when high pull-out strength is required in thermoplastic materials. The straight flanged profile provides better retention than tapered designs in certain plastics. Confirm that the substrate material can withstand the thermal energy used during heat-staking or ultrasonic welding processes without deformation.

Part Context

This component belongs to the E-Z Lok series of heat-installed threaded inserts. These inserts are engineered to create permanent, strong metal threads within plastic components. The FL-440-HI-CR specifically addresses inch-threaded applications requiring robust mechanical performance in plastic assemblies.

Replacement Considerations

Direct substitutes must match the #4-40 thread size, straight flanged geometry, and stainless steel construction. Verify that alternative inserts support the same installation method (ultrasonic or heat) and fit the 0.157 inch pilot hole requirement to maintain assembly integrity.
