BRASS THREADED INSERTS FOR INJECTION-MOLDED PARTS
These brass inserts provide a durable internal metal thread inside plastic housings and molded components. They are normally positioned in the mold before plastic injection or installed using a project-specific assembly method.
The external profile can include grooves, knurling, shoulders, flanges or stepped diameters. These features help control insert position and improve resistance to rotation and axial movement inside the surrounding plastic.

Application Considerations
The insert dimensions should be matched to the plastic material, molding process, wall thickness and expected assembly load. Pullout resistance and torque resistance depend on the external retention profile and surrounding plastic structure.
Typical Applications
Suitable for plastic housings, electrical equipment, instruments, appliances, control components, automotive plastic parts and other molded assemblies requiring a reusable metal thread.
