  • Especially efficient for brittle or weak plastics

Available from stock in Brass

Custom sizes/materials available

TRISERT Coarse Threaded Inserts are internally and externally threaded metal inserts designed to meet the increased demand for holding power in thermoplastic and thermosetting plastics. The wider spaced external threads reduce installation torque and provide a stronger hold. Installation is simple, as three external flutes provide full cutting action, while retaining chips to keep inside threads clean.
