C Series: Chevron Threaded Inserts for Plastics and Brittle Materials

Chevron Threaded InsertSome thermoplastics, like polycarbonates and structural foams, are brittle – especially in thin-wall applications. Designed for straight holes using ultrasonic or thermal processes, our chevron threaded inserts for plastic add considerable strength. They are our most popular brass inserts, offering the most overall length choices.

Our chevron inserts feature two opposing bands of sharp diagonal knurls, providing high tensile pull-out load carrying capability. Little or no stress is applied to the walls of the molded holes. A lead-in pilot diameter assures true perpendicular alignment.

Recommended Hole Size – See chart to the right for installation hole size. Additional information can be found in our Design Guidelines.
