Pressure - THREADED INSERTS FOR PLASTICS

Press Inserts are designed to be pressed into a straight hole without melting the plastic prior to installation. The helical grooves of the Press Inserts, ideal for use in softer plastics, are used to provide resistance to torsion and extraction, and to ensure good plastic flow as the Insert rotates in the hole. The torque required to achieve sufficient tension between the threads is not an issue, as the helical grooves are designed so that the direction of the tightening torque tends to push the insert into the hole - which, of course, is not possible - as the threaded joint is tightened. A pilot that is slightly smaller than the hole and of sufficient length is designed to ensure straight insertion into the hole. Press inserts offer quick installation without specialized equipment and achieve good overall performance of the joint.
