Procurement Notes

Verify the specific material grade and dimensional tolerances against the official E-Z LOK datasheet before procurement. Confirm that the ultrasonic welding equipment parameters match the requirements for stainless steel inserts. Ensure the target thermoplastic material is compatible with the specified insertion method and thermal limits.

Selection Notes

Select this model when stainless steel strength and corrosion resistance are required over brass alternatives. Ensure the application involves thermoplastics suitable for ultrasonic insertion. Verify that the #1/4-20 thread size meets the fastener requirements. Consider the straight flanged design for applications needing robust pull-out resistance.

Part Context

This part belongs to the E-Z Sonic series of ultrasonic threaded inserts manufactured by E-Z LOK. These inserts are engineered specifically for integration into plastic components using ultrasonic energy. The series offers various materials and thread sizes to suit different mechanical and environmental demands in plastic assembly applications.

Replacement Considerations
