Threaded Inserts for Plastics provide reusable threads and secure tight threaded joints. An additional benefit is high load carrying capability. The objective is to design an Insert with sufficient torque resistance to accommodate the tightening torque necessary to achieve sufficient axial tension load on the threaded joint to keep it together and prevent loosening, while also achieving pull-out values necessary for the load conditions that the Insert will be exposed to while in service.
SPIROL’s Inserts are designed to maximize and balance rotational torque and tensile (pull-out) performance. We provide complimentary Application Engineering support to help you design in the most appropriate Insert for your plastic assembly.
SPIROL offers a variety of Threaded Inserts for Plastics to meet your performance and installation requirements including heat/ultrasonic, molded-in, press-in and self-tapping Inserts in standard thread sizes ranging from M2 (2-56) to M8 (5/16-18) – depending on Insert type.
