The E-Z LOK FL-518-HI-CR is a heat-set and ultrasonic threaded insert designed for post-molding installation in thermoplastic materials. It features a straight body with a flanged design to prevent rotation during installation. The component is machined from high-quality brass, providing superior torque and pull-out resistance. The internal thread size is 5/16-18. This insert allows for the creation of durable metal threads in plastic substrates using either ultrasonic energy or a heat driver.
Verify the specific suffix 'CR' against the manufacturer's datasheet to confirm material composition details, as it may denote stainless steel threads or specific plating. Ensure compatibility with your ultrasonic or heat staking equipment specifications before procurement.
Select this model when a straight profile with a flange is required for anti-rotation stability. The 5/16-18 thread size suits medium-duty fastening needs. Consider the brass body material for general thermoplastic applications where corrosion resistance is not the primary constraint.
This part belongs to the E-Z Sonic series of ultrasonic threaded inserts. These inserts are engineered specifically for integration into plastic parts after the molding process. The series offers various thread sizes and body designs to accommodate different assembly requirements.
Direct substitutes must match the 5/16-18 thread size, straight flanged geometry, and brass construction. Verify that alternative brands support both ultrasonic and heat-stake installation methods to ensure functional equivalence.
