Series 29 heat-ultrasonic threaded inserts for plastics are designed to provide reusable threads and enhanced load-carrying capability in plastic substrates, with a brass or aluminum thread offering creep resistance and improved pull-out performance. The inserts are installed via heat or ultrasonic methods and feature a body diameter larger than the mating screw to increase shear surface area. They are engineered to maintain joint integrity under stress relaxation conditions common in plastics and support proper assembly torque without loosening. The series is part of SPIROL's broad range of inserts optimized for tensile and rotational torque performance.
Series 29 Standard and Series 30 Flanged — Symmetrical for ease of orientation and enhanced performance designed to maximize torque and pull out values.
