E-z Lok FL-124-HI Brass Threaded Insert 10-24 Unc

Product Description

The E-Z LOK FL-124-HI is a headed, heat-installed threaded insert made from brass, designed to create durable internal threads in thermoplastic components. The insert measures 0.278 inches in diameter and 0.418 inches in overall length, with a head diameter of 0.312 inches and a head height of 0.040 inches. It accepts a 10-24 UNC thread standard, making it compatible with standard machine screws used across a wide range of assemblies. Installation is performed by pressing the insert into a pre-drilled pilot hole using a calibrated heat source, such as a soldering iron or heat press, which softens the surrounding material and allows the insert to seat flush or countersunk into the part.

This insert is used in applications where a reliable threaded connection is needed in a plastic housing, enclosure, bracket, or panel. It is well suited for light industrial, HVAC controls, electrical enclosures, and plumbing fixtures manufactured from thermoplastic materials. The brass construction resists corrosion and provides consistent thread engagement across repeated assembly and disassembly cycles. Technicians working in manufacturing, assembly, or field repair applications will find this insert appropriate wherever a secure fastener anchor is required in a plastic substrate.

Key Features

• 10-24 UNC internal thread standard for compatibility with common machine screws
• Brass construction for corrosion resistance and strong thread retention
• Headed design provides a positive stop during installation for consistent seating depth
• Heat-installed method bonds insert securely into thermoplastic by displacing material around knurled body
• 0.418 inches overall length with 0.278 inches insert diameter suits typical thin-wall plastic applications
• Minimum wall thickness of 0.102 inches accommodates common plastic panel and housing designs

Compatibility

Designed for heat-installed use in thermoplastic substrates requiring a 10-24 UNC threaded insert with a 0.252 inch hole diameter and 0.277 inch pilot diameter.

Installation Notes

Installation is performed by a technician using a temperature-controlled heat source or ultrasonic press calibrated for the target thermoplastic material. The host part must be drilled or molded to the specified pilot hole diameter before insertion. Power down any associated equipment and allow components to cool before handling installed inserts. Do not exceed the recommended installation temperature for the base material, as overheating can degrade thread pull-out strength.
