Yardley TRISERT Coarse Threaded Inserts are internally and externally threaded metal inserts designed to meet the increased demand for holding power in thermoplastics, thermoset plastics, soft metals and wood. 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.
