Heavy Duty Threaded Insert: These brass threaded inserts are made of high quality brass, providing excellent corrosion resistance, high strength and long service life. Designed as thermal inserts for plastic, they remain firmly anchored in the material Simple installation: Heat insertable threaded inserts can be easily installed in plastic parts or parts from 3D printing using a heating iron, heat treatment or ultrasound. The good thermal conductivity of brass allows the plastic to soften evenly for precise insertion Strong and reliable attachment: The knurled outer surface with diagonal profile increases friction in the plastic and guarantees excellent holding force. Precision internal thread ensures reliable connection with screws and effectively limits vibration loosening Wide material compatibility: These threaded inserts for plastic are compatible with common thermoplastics such as PLA, PETG, ABS, PPS and PP. They are widely used in 3D printing, electronic housing, automotive components, household appliances and PCB assembly Practical accessories: This set includes 20 threaded inserts M4 x 8.1 x 6.3 mm, sufficient for daily use and replacement needs.
